Optimization and Analysis of InGaAs Vertical Nanowire Transistor for Memory Array Applications
Abstract: In this paper, we present a cylindrical gate all around In 0.53 Ga 0.47 As Vertical Nanowire Transistor (VNWT) on silicon at ultra-shortchannel gate length 14nm by numerical simulation approach. The In 0.53 Ga 0.47 As VNWT device dimensions like diameter, source and drainextension length and channel doping are taken as critical process parameters and optimized for better performance. The proposed device isscalable up-to 10nm with a maximum On-current of …

Design and Performance of Semiconductor-Biosensor
Abstract: In this work, a high electron mobility transistor (HEMT) based biosensor is designed to detect the virus-protein. In this work, all the simulation-studies are carried out in the SILVACO-ATLAS physical simulator using the following models: Shockley Read Hall (SRH), band gap narrowing, Auger recombination, and Fermi Dirac statistics. Newton trap numerical solver is used in the device simulation. Conduction band engineering of the biosensor is studied. DC and RF properties …

Experimental Investigations to Improve the Electrical Characteristics of Nitride-Based Nanoelectronic High Electron Mobility Transistors
Abstract: In this work, the DC and RF performances of conventional nanoelectronic high electron mobility transistor (HEMT) are compared with those of two individually modified HEMT structures in a nano-scale regime. All simulation results are produced by the SILVACO- ATLAS physical simulator according to the performed designs of HEMT structures. In each of these HEMT structures, the formation of quantum well is demonstrated at unbiased condition. In the DC analysis of …
