Michigan State University (MSU) will develop high-voltage diamond semiconductor devices for use in high-power electronics. Diamond is an excellent conductor of electricity when boron or phosphorus is added—or doped—into its crystal structures. It can also withstand much higher temperatures with higher performance levels than silicon, which is used in the majority of today’s semiconductors. However, current techniques for growing doped diamond and depositing it on electronic devices are difficult and expensive. MSU is overcoming these challenges by using an innovative, low-cost, lattice-etching method on doped diamond surfaces, which will facilitate improved conductivity in diamond semiconductor devices.
If successful, MSU’s innovative diamond growth technique will facilitate low-cost semiconductor devices capable of conducting enough electricity for high-power electronics.
Advances in power electronics could facilitate greater adoption of electric vehicles, which in turn could help reduce U.S. oil imports.
More efficient power electronics systems promise reduced electricity consumption, resulting in fewer harmful energy-related emissions.
More efficient power electronics would use less energy, saving American families and business owners money on their power bills.
