BPN704: Vapor-Liquid-Solid Growth of Polycrystalline Indium Phosphide Thin Films on Metal

Wenbo Ji
2021

Here, we develop a technique that enables direct growth of III-V materials on non-epitaxial substrates. Here, by utilizing a planar liquid phase template, we extend the VLS growth mode to enable polycrystalline indium phosphide (InP) thin film growth on Mo foils.

BPN935: Low Temperature Deposited Thin Films for p-Type Field Effect Transistors and Circuits

Chunsong Zhao
2021

Developing low-temperature grown semiconducting films is critical for the development of flexible, transparent and three-dimensional monolithic integrated electronics, however, low processing temperature typically results in a poor crystallinity and a low mobility. Here, we report the realization of low-temperature fabrication of highly crystalline tellurium films with large grain size (average grain area of ~150 um2) by controlling the crystallization process of thermally evaporated Te films. Tellurium single crystals with a lateral dimensional of 6 um are realized on various...

2011

High electron mobility III-V compound semiconductors such as indium arsenide (InAs) are promising candidates for future active channel materials of electron devices to further enhance device performance. In particular, compound semiconductors heterogeneously integrated on Si substrates have been studied, combining the high mobility of III-V semiconductors and the well-established, low cost processing of Si technology. However, one of the primary challenges of III-V device fabrication is controllable, post-growth dopant profiling. Here InAs nanowires and ultrathin layers (nanoribbons...

2018

Device architecture and materials innovations have enabled transistor scaling for the last several decades, boosting the performance of electronics, increasing the speed of communication and computational systems, lowering power consumption and reducing costs per operation. Two-dimensional (2D) materials have gained tremendous attention in the last decade, after the discovery of graphene which has exceptional properties like high carrier mobility, ultra-thin van der Waals connected layers (~ 0.3 nm thick), high tensile strength, etc.

2013

Since the beginnings of the semiconductor revolution, device engineering and material development have been deeply interconnected. Innovations in one invariably spurred development in the other. One of the most important current challenges are developing techniques which enable deposition of materials on arbitrary substrates and the design constraints of devices fabricated via these techniques. This thesis focuses on furthering the materials development-device design cycle for three techniques: (i) epitaxial lift-off, (ii) nanowire growth via the vapor-liquid-solid growth mode, and (...
