Scientists at the Lawrence Livermore National Laboratory in the US published a study in
Applied Physics Letters where they present the idea of using diamonds as ultra-wide bandgap semiconductors to more effectively power the electrical grid, locomotives and even electric cars.
In their paper, the researchers said that diamonds have been shown to have superior carrier mobility, breakdown electric field and thermal conductivity, the most important properties to power electronic devices. The gems also became especially desirable after the development of a chemical vapor deposition process for the growth of high-quality single crystals.

When it comes to the semiconductor industry, silicon has reigned as king in the electronics field, but it is coming to the end of its physical limits.
To more effectively power the electrical grid, locomotives and even electric cars, Lawrence Livermore National Laboratory (LLNL) scientists are turning to diamond as an ultra-wide bandgap semiconductor.
Diamond has been shown to have superior carrier mobility, break down electric field and thermal conductivity, the most important properties to power electronic devices. It became especially desirable after the development of a chemical vapor deposition (CVD) process for growth of high-quality single crystals.
