Self-Aligned Heterojunction Diodes and Transistors

Description:

Low-dimensional materials have emerged as a promising platform for ultrathin electronic and optoelectronic devices. The span of electronic properties covers the spectrum from metallic through small and medium bandgap semiconductors to large bandgap insulators, providing all the necessary components to fabricate a variety of devices. Compared to bulk-semiconductor based devices,...

Phototransistors Based on III-V Semiconductors and Low-Dimensional Materials for High-Speed Imaging at High Operating Temperatures

Description:

In this thesis, the optical gain mechanism in low-light conditions of phototransistor detectors (PTDs) is explored. An analytical formula is derived for the physical limit on the minimum number of detectable photons for PTDs. This formulation shows that the sensitivity of the PTD, regardless of its material composition, is related...
