GaN-based light-emitting diodes (LEDs) on sapphire are known to exhibit high efficiency and long lifetime. In order to fabricate the cost-effective LEDs on larger scale, the most efficient approach is the growth of scalable and high crystal quality GaN nanowires on amorphous substrate, preferably glass. We have demonstrated the growth of GaN nanowire-based LEDs using metal-organic chemical vapor deposition on an amorphous glass substrate. Additionally, the InGaN/GaN multiple quantum well shells are conformally grown on semipolar (1122) growth facet of m-axial GaN core nanowires and resulted in reduced quantum confined Stark effect. The photoluminescence spectroscopy of the GaN core nanowire-ensemble reveals a very high crystal quality due to the dominant emission from the band-to-band transition and absence of a characteristic yellow luminescence.

With the advent of Internet-of-Things (IoT), the conventional radio frequency (RF) communication technology with a congested spectrum of 300 GHz cannot meet the ever-increasing demand for broadband transmission. By exploiting an unlicensed spectrum of ~ 30 PHz, optical wireless communication (OWC) technology is supposed to significantly relieve the load of RF spectrum to support the massive connectivity of IoT devices in the era of fifth-generation networks and beyond. Up to now, continuous breakthroughs in the field of free-space optical communication, visible light communication, and underwater wireless optical communication (UWOC) are laying a solid foundation for the realization of OWC across satellite-air-ground-ocean (SAGO) boundaries, which is expected to considerably accelerate the pace of realizing globally-connected IoT. In this talk, we will briefly introduce the current progress of UWOC research and development toward applications in SAGO OWC.

In this speech, In this speech, Okumura-Hata expressions will be presented for calculating the attenuation of the field strength of mobile communication stations in the megapolis on the example of the capital of Uzbekistan - Tashkent in the frequency bands 900 and 1800 MHz. Expressions allow to take into account factors that affect the signal attenuation in detail. Knowing the levels of the distribution patterns of the field strength in urban environments can correctly determine the number of base stations required to provide high-quality mobile communication. High quality of mobile communications, in turn, creates the best conditions for a quick payback on the development of a mobile network.

In this talk we discuss approaches to low power design for advanced communication and computing platforms. Specifically, we present the concept of cognitive power management, where contrary to common approaches that assume a 100% error free hardware, the algorithm is made aware of the statistical error performance of the underlying hardware platform. By accounting for hardware errors at the system level, the explorable power management design space is significantly expanded, leading to novel power saving schemes that deliver expected application performance at much lower power consumption.  Sample case studies including LTE system design and in-memory computing platforms will be presented and discussed.

Africa has one of the highest inequality factors in the world, reflecting its developed and developing nature. As such it suffers from the traditional “digital divide”, with low internet connectivity reach in rural areas, which is both economic and geographic in nature. In this talk we will summarize recent proposals to bridge the digital divide and offer a South African perspective on the problem. We will cover active research in South Africa on the topic and speculate what the network future in Africa might be.

Although there is a rich history of cross-layer design for embedded computing systems to achieve desired QoS, we are facing ever more challenges from the intertwined goals of energy- efficiency, thermal design constraints, as well as resilience to errors emanating from the application, environment and hardware platforms. We posit that next-generation computing platforms must necessarily deploy intelligent cross-layer design achieved through self-awareness principles inspired by biology and nature.  Such an approach will move us from current strategies (using limited cross-layer coordination) to a holistic cross-layer strategy that enables intelligent cross-layer management policies which can adaptively tune itself based on the current state of the system. The talk will present design exemplars that embrace this intelligent cross-layer approach, and highlight the role of self-awareness in achieving dynamic adaptivity.

The talk will discuss how recent advances in wireless computing and communication nodes can be harnessed to serve the multitude of deployment scenarios required to empower communities of the future with smart and connected systems. In this talk, we address fundamental questions that should be asked when contemplating future smart and connected systems, namely, How, Where and What? (1) How can we design computing and communication nodes that best utilize resources in a way that is cognizant of both the abilities of the platform, as well as the requirements of the network? (2) Where are the nodes deployed? By understanding the context of deployment, one can architect unique solutions that are currently unimaginable. With the transformation to diverse applications such as body area networking, critical infrastructure monitoring, precision agriculture, autonomous driving, etc., the need for innovative solutions becomes even more amplified. (3) What benefit can be inferred from the data gathered by nodes in the capacity of computing, communication, and sensing?

Physically compliant electronics are scientifically intriguing, mechanically complex, ‎technologically ‎challenging but with huge socio-economical potential. Until now the target applications ‎for ‎flexible electronics have been limited to displays, solar cells, printed batteries, wearables, and ‎implantable. However, with the emergence and growth of Internet of Things (IoT) devices ‎worldwide ‎from nearly 27 billion in 2017 to 125 billion in 2030, in this PhD research, expanding the ‎horizon of ‎applications for flexible electronics toward existing “things” will be explored. Low-cost sustainable materials as active electronic materials and a ‎Do-It-Yourself (DIY) integration strategy is used to build “Add-on” standalone sensory system which can be ‎attached to any ‎existing things like a decal. Such electronics can also be embedded in newly minted ‎devices specially ‎using additive methods.

Power constraint has become a critical challenge for computing, restricting the rate at which data can be processed. The physics of ordered and correlated systems allow for fundamental improvement of the energy efficiency in this regard, going beyond what is possible with conventional materials in today’s computing hardware. One such example is the the ferroelectric materials, where thermodynamics dictate that charge can be switched with much lower energy compared to conventional dielectrics. This leads to a situation where a ferroelectric material can be stabilized at a state of negative capacitance. In this talk, I shall discuss our experimental work demonstrating the stabilization of negative capacitance, its integration into advanced transistors, and its potential impact on next generation computing hardware.

In this seminar, I will present the first wafer-scale statistical analysis of memristive crossbar arrays made of 2D layered materials. By using chemical vapor deposited multilayer hexagonal boron nitride (h-BN) sheets, we have fabricated metal/h-BN/metal memristive crossbar arrays that exhibit high yield ~98%, and low device-to-device variability. The devices showed record electrical performance, including stable operation at ultra-low currents down to 110 fA in low resistive state, ON/OFF current ratios up to 1011, record non-linearity of <0.09 mV/decade, and unprecedented low energy consumption down to 4.4 zJ/transition. Furthermore, the miniaturization of metal/h-BN/metal memristors has been demonstrated by using nanodot (Ø < 50 nm) electrodes. These findings may accelerate the use of 2D materials for building wafer-scale and high-density electronic memories and artificial neural networks.
