Abstract
A new emission band at is observed in Si using carrier injection in a device. The extremly weak photon emission was detected by a special differential counting technique. From the photon energy, the quadratic dependence on the excitation intensity, and the weak temperature dependence, it is concluded that the observed emission is caused by a two-electron transition.
