However, the forward voltage drops of these devices increases quickly with increasing breakdown voltage. Minority carrier devices, including the BJT, IGBT, and thyristor family, can exhibit high breakdown voltages with relatively low forward voltage drop. However, the switching times of these devices are longer, and are controlled by the times needed to insert or remove stored minority charge. Energy is lost during switching transitions, due to a variety of mechanisms. The resulting average power loss, or switching loss, is equal to this energy loss multiplied by the switching frequency.

Switching loss imposes an upper limit on the switching frequencies of practical converters. You just clipped your first slide!

I recognized then that diamond technology could spark a seismic change in the electronics industry and I knew I wanted to play a role in making diamond semiconductor a reality. Then, as now, silicon had been the popular material choice for semiconductor since the s, and it still constitutes 95 percent of the device types available in the market.

But it presented several long-term challenges. The still more pressing and visible problem in silicon was that of heat. Historically, heat management with silicon semiconductor devices has proven problematic for power electronics. The cooling methods required were inefficient and served as a major source of e-waste.
The industry required a silicon alternative that enabled devices to be smaller, cooler, faster, more powerful, and cleaner. That defines the diamond semiconductor.
No longer just relegated to gem stone status, diamond provides a road map for an unknown number of years ahead in power electronic development and more broadly the global electronics industry. Indeed, many consider that the industry is entering the Dawn of a Diamond Age of Electronics. Why diamond?
It can run hotter without degrading in performance over 5 times that of Silicon , is more easily cooled with 22 times the heat transfer efficiency of silicon , can tolerate higher voltages before breaking down, and electrons and electron-holes can move faster through them. Already, semiconductor devices with diamond material are available that deliver one million times more electrical current than silicon or previous attempts using diamond. Diamond-based semiconductors are capable of increasing power density as well as create faster, lighter, and simpler devices.

As a result, the diamond materials market for semiconductors can easily eclipse that of the Silicon Carbide, which is seen growing at a A little over a decade since that research paper sparked my interest, my company AKHAN SEMI, in collaboration with Argonne National Laboratory, has developed a series of advancements that allows us to manufacture standalone diamond materials, deposit diamond directly on processed silicon, fabricate complete diamond semiconductor devices, as well as attach diamond material to other electronics materials.
Diamond wafer technology is producing thinner and cheaper devices already in use in information technology, the military and aerospace applications. In addition, diamond semiconductor will have a major impact on the consumer electronics, telecommunications and health industries, among many others, starting as early as Automakers are eyeing applications of diamond power devices in control modules for electric cars. Diamond semiconductors can also help better manage battery life and battery systems for a wide variety of devices including phones, cameras and vehicles.
For cloud computer servers, which are stored in data centers that consume vast amounts of energy in an exceedingly wasteful manner, diamond semiconductors use less energy more efficiently while delivering better performance. Because diamond technology shrinks the size and energy needed for a semiconductor, it paves the way for smaller personal electronics from washers and dryers to televisions and digital cameras. As a result, diamond semiconductors lead to a greater range and energy efficiency in their applications.
