Research

Our research is focused on development of integration strategy for rational design of materials, processes, devices, characterization methodology and equipment for innovation of new applications based on physical electronics and internet. We use heterogeneous electronic materials and high-performance complementary metal oxide semiconductor (CMOS) based tunable shape-size-conformity interactive electronics and systems for smart living (computation-communication-infotainment) through internet of everything and a sustainable future (healthcare-water-food-environment-security). For scientific exploration, we make collective use multidisciplinary electrical engineering, material science, bioengineering, mechanical engineering, environmental engineering, plant, marine and computer science. As engineering tool, we use CMOS technology extensively due to its industrial relevance, maturity and reliability for rapid tech transfer.

 

Our present expedition includes but not limited to:

1. Free form electronic systems (predominantly based on CMOS): Flexible-stretchable-reconfigurable-embedded-adaptable electronics.

Applications are specifically focused on: (a) Internet of Everything; (b) Brain Machine Interface; (c) Human Machine Interface; (d) Advanced and Low Cost Healthcare; (e) Interactive Computation. [Supported by many funding agencies and international industries]

[We are the only group who have CMOS based technologies to transform any state-of-the-art electronics into flexible, stretchable and reconfigurable one while retaining their high performance, energy efficiency, ULSI density and relative low-cost due to CMOS based batch processing]

2. II-IV and III-V nanotube FET and wavy transistors (for HP, TFET and TFT). [Supported by KAUST] [The concept of Si, SiGe, III-V was first coined and demonstrated by our group]

3. Advance healthcare applications using microbial fuel cells. [Supported by KAUST OCRF] [Highlighted by Scientific American as one of the Top 10 World Changing Ideas 2014]

4. Amorphous metal based NEMS. [Supported by KAUST OCRF, formerly supported by US DARPA]

We are the only group using amorphous metal.

5.. Using 2D materials for sustainable technology. [Supported by Boeing and Lockheed Martin]

Current Reseach

Vertically aligned multi-walled carbon nanotube (MWCNT) anode and nickel silicide (NiSi) integrated micro-sized 1.25 uL silicon microbial fuel cell with tremendous output current (197 mA/m2 from uL scale device), generating power densities of 392 mW/m3 with carbon cloth as cathode, mixed bacteria culture as inoculum and ferricyanide as catholyte.
We are using CVD based growth of graphene at atmospheric pressure to develop novel but simple metrology for graphene characterization. In conjunction with that, we are also working on module process development like contact and dielectric-graphene interface engineering. Our next phase goals include pattern directed growth of graphene and device integration.
‚ÄčThe first ever energy- reversible lateral nanoelectromechanical switch. We have also developed amorphous metal with low tensile stress to open a new paradigm of NEM switch and systems.
A new device architecture silicon nanotube field effect transistor (FET) with its unique core-shell gate stacks help achieving full volume inversion by giving a surge in minority carrier concentration in the near vicinity of the ultra-thin channel and at the same time rapid roll-off at the source and drain junctions constituting velocity saturation induced higher drive current induced performance per device with efficient real estate consumption.
