Course title: Wide bandgap Semiconductor Devices (WBG-Devices)

 

Are we prepared for the Next generation electronics?

When we say “Next Gen”- we are talking “Beyond Si”

Widebandgap (WBG) semiconductors present a pathway to push the limits of efficiency in electronics beyond that available from Silicon or other commercially used semiconductors, enabling significant energy savings.. Increasing efficiency is not only critical for minimizing consumption of limited resources; it simultaneously enables new compact architectures, the basis for a new industry offering more functionality at a reduced system cost. This coursework attempts to answer the rhetorical question that the electronics industry is asking today- what is the path beyond Silicon by providing a clear picture on the limitations of Silicon and advantages of semiconductor devices those are built with wide bandgap semiconductor. We will thoroughly discuss the operation principle of these WBG enabled devices, their performance, their current and potential application space, and their demands in the market. We will discuss semiconductor materials to the extent required to understand these devices. The course work will discuss devices based on Gallium Nitride and other III-Nitrides, Diamond and Oxide. The term papers will include two short projects that will require simulation to conduct device design and analysis

Prerequisite: Graduate Standing in Engineering, EEC 140B

Expanded Course Description:

The course attempts to answer the rhetorical question that the electronics industry is asking today- what is the path beyond Silicon? This coursework is designed to answer the question by providing a clear picture on the limitations of Silicon and advantages of semiconductor devices those are built with wide bandgap semiconductor. The course will thoroughly discuss the operation principle of these WBG enabled devices, their performance, their current and potential application space, and their demands in the market. We will discuss semiconductor materials to the extent required to understand these devices. The course work will discuss devices based on Gallium Nitride and other III-Nitrides (70%), Diamond (20%) and Oxide (10%). The term papers will include two short projects that will require simulation to conduct device design and analysis.Roadmap and market of wide bandgap semiconductor
