Implication

Experimental study demonstrates a method to measure trapped-minority-carrier thermal emission rates in doped silicon diodes, indicating accurate trap profiling using a single p-n junction.

Key Points

To measure the thermal emission rates of trapped minority carriers from gold, silver, and cobalt impurity centers in silicon diodes using an optical excitation technique.
Fabricated reverse-biased n+p silicon diodes doped with gold (Au), silver (Ag), and cobalt (Co).
Applied monochromatic light of appropriate photon energy to partially fill deep traps with minority carriers (electrons), then measured subsequent thermal emission rates after turning off illumination.
Demonstrated direct experimental observation and measurement of minority-carrier thermal emission rates following optical excitation.
Enabled accurate determination of thermal emission rates for both minority and majority carrier traps within a single p+n or n+p junction.
