Japan's National Institute of Advanced Industrial Science and Technology (AIST) developed a deep UV LED that uses a diamond semiconductor.
AIST plans to unveil the details at the 56th Spring Meeting, 2009 of the Japan Society of Applied Physics, which will take place from March 30 to April 2, 2009, in Ibaraki Prefecture, Japan.
The deep UV LED is composed of a 2mm-square diamond substrate on which a p-i-n-structured diamond semiconductor is stacked. It emits deep ultraviolet light with an emission wavelength of 235nm. The output is 30μW when a 320mA current is supplied.
