Research

We are a research group in the department of Electrical and Computer Engineering at New York University led by Professor Shaloo Rakheja. Our research focus is on using new physical concepts, new materials, creative devices, circuits and architectures to improve system functionalities in the existing semiconductor technologies and implement completely new nano-systems for maximum benefit. We have three main focus areas of research summarized below.


  • FOCUS I: Electronics: We are developing physics-based models to describe static and dynamic characteristics of ultra-scaled transistors including ETSOI, III-V HEMTs, III-ntride HEMTs, ambipolar graphene, and ambipolar black phosphorus transistors.
     
  • Focus II: Plasmonics: One of the most potentially significant and transformative applications of terahertz (THz) technology is in wireless communication owing to the extremely high bandwidth of the THz band, ranging from tens to thousands of GHz depending on the signal trans- mission distance. So far, the biggest challenge toward using the THz band for technological applications has been the lack of suitable THz sources and detectors. Fortunately, two-dimensional (2D) material systems exhibit strong light-matter interaction over frequencies ranging from microwave to the ultraviolet. In our research, we use light manipulation and guiding in 2D materials at THz frequencies to enable energy-efficient and high-bandwidth wireless communication in next-generation nano-systems.
     
  • Focus III: Magnetics: Magnetic devices offer (i) non-volatility to reduce static power dissipation, (ii) tunable and fast nonlinear dynamics, (iii) controlled stochasticity and noise tolerance, and (iv) ability to realize multiple functions using the same device layout, i.e. they are inherently polymorphic. In our research, we study spin-dependent phenomena (spin transport, spin relaxation, topological spintronics), magnetization dynamics (effect of noise, dipolar coupling), and applications of spin-based devices to reconfigurable and secure electronics.
