Enhanced Room-Temperature Geometric Magnetoresistance in Inhomogeneous Narrow-Gap Semiconductors.

A symmetric van der Pauw disk of homogeneous nonmagnetic indium antimonide with an embedded concentric gold inhomogeneity is found to exhibit room-temperature geometric magnetoresistance as high as 100, 9100, and 750,000 percent at magnetic fields of 0.05, 0.25, and 4.0 teslas, respectively. For inhomogeneities of sufficiently large diameter relative to that of the surrounding disk, the resista...

Inter-band Tunnel Transistor Architecture using Narrow Gap Semiconductors

The inter-band tunnel transistor (TFET) architecture features a subkT/q sub-threshold slope operation and can potentially support high ION/IOFF ratios over small gate voltages. Based on twodimensional numerical simulations, we investigate TFET in various material systems ranging from silicon to indium arsenide. TFET performance can be enhanced when heterojunctions are employed at the source sid...

Computational Studies of Compressed Diborane and Engineered Narrow-Gap Semiconductors

The research contained in this thesis is two-fold: understanding the behavior of dib-orane under pressure, and engineering wide-gap semiconductors in order to promotetheir optical e ciency. Each of these themes are further explained below.Diborane (B2H6), is a prototypical electron-deficient molecule and has received a greatdeal of attention in recent years due to its unique and...
