Recombination lifetimes in gamma-irradiated silicon
… were measured as a function of temperature in silicon before and after irradiation at room temperature by cobalt 60 gamma rays. The resistivity of the boron doped samples ranged between 10 and 5000 ohm-cm, and the resistivity of the phosphorus doped samples was between 20 and 220 ohm-cm. Both …

Infrared absorption of neutron irradiated silicon
In this work the infrared absorption of neutron irradiated silicon was compared to that of non-irradiated silicon at room and liquid nitrogen temperatures. It was found that instead of the 1.75 micron absorption band that has been mentioned in numerous papers transmission was completely cut off …

The effect of stress on the luminescence spectrum of irradiated silicon
Silicon crystals which have been irradiated with neutrons, high energy electrons, or gamma-rays at room temperature show two strong luminescence bands in the near infrared. Both bands have a sharp zero-phonon line followed by a series of broad phonon assisted peaks. The higher energy band …

A theoretical and experimental investigation of the annular jet ground effect machine
In this work the infrared absorption of neutron irradiated silicon was compared to that of non-irradiated silicon at room and liquid nitrogen temperatures. It was found that instead of the 1.75 micron absorption band that has been mentioned in numerous papers transmission was completely cut off …
