Device scaling has been one of the main driving forces for technology advancement in the semiconductor industry over last few decades. As this scaling continues into the future, serious fundamental and technological issues will arise as a result of the limitations of conventional device fabrication and materials, etc. Among these many challenges, in particular, there is a tremendous need for new processing technologies to control atomic composition in semiconductor structures as well as the application of new...

Nutrients are essential for the healthy development and proper maintenance of body functions in humans. For adequate nourishment, it is important to keep track of nutrients level in the body, apart from consuming sufficient nutrition that is in line with dietary guidelines. Sweat, which contains rich chemical information, is an attractive biofluid for routine non-invasive assessment of nutrient levels. Herein, a wearable sensor that can selectively measure vitamin C concentration in biofluids, including sweat, urine, and blood is developed. Detection through an electrochemical sensor...

Two-Dimensional Semiconductor Optoelectronics

A fundamental figure of merit for high performance optoelectronic devices is their photoluminescence (PL) quantum yield (QY). This value, which accounts for the fraction of absorbed photons are re-emitted by the material governs the ultimate performance of optoelectronic devices such as light emitting diodes, photodetectors/photovoltaics, and solar cells. Two-dimensional (2D) semiconductors have emerged as a promising material system for high-performance optoelectronic and electronic applications. This class of materials possess out-of-plane van der Waals bonding, and as a result has...

Expanding the Scalability and Applications of III-V Optoelectronic Devices by Evolution of Thin-Film Vapor-Liquid-Solid Growth

Mark Hettick
2019

Semiconductor materials are a constant limitation and avenue of improvement for the performance and efficiency of electronic and optoelectronic devices. Nowhere is this clearer than in the parallel fields of microelectronics and photovoltaics, where scaling and optimization of silicon-based systems has dominated tangible innovation in their respective markets for decades. While III-V materials have made inroads in both high efficiency photovoltaics and hybrid opto-electronic circuits, they are traditionally limited in terms of scalability and cost due to the expense of lattice-matched...
