Ever since the invention of the transistor, aggressive channel length scaling has been pursued to achieve higher performance and greater packing density. In order to preserve gate control at short channel lengths, the transistor channel has evolved from bulk to low dimensional substrates, such as 2D thin films and 1D nanowires. For scaling to continue, it is vital that we understand the processing and physics of low dimensional materials.

Chapter 2 focuses on quasi-2D ultrathin body InAsSb-on-insulator n-FETs. III-V materials offer high mobilities for excellent on-state currents,...

Wireless technology, which already plays a major part in our daily lives, is expected to further expand to networks of billions of autonomous sensors in coming years: the so-called Internet of Things. In one vision, sensors employing low-cost, low-power wireless motes collect and transmit data through a mesh network while operating only on scavenged or battery power. RF MEMS provides one approach to the stringent power and performance required by sensor networks.

This dissertation presents improvement to these MEMS technologies and introduces new approaches for wireless...

With the rise of the Internet of Things (IOT), demand for novel devices and sensors for a variety of applications has exploded, and as a result, there is a need for the development of new processing schemes and materials systems to accommodate the expanding needs of these applications. In particular,

Chapter 2 explores the growth of III-V semiconductors with quality approaching that of epitaxial thin films directly onto amorphous substrates using a new growth mode known as template liquid phase (TLP) crystal growth. The fundamental theory and limitations of TLP...

In recent years, the photovoltaic market has grown significantly as module prices have continued to come down. Continued growth of the field requires higher efficiency modules at lower manufacturing costs. In particular, higher efficiencies reduce the area needed for a given power output, thus reducing the downstream balance of systems costs that scale with area such as mounting frames, installation, and soft costs. Cells and modules made from III-V materials have the highest demonstrated efficiencies to date but are not yet at the cost level of other thin film technologies, which...
