摘要：

We describe the laser-induced breakdown in xenon gas, or at an air/glass interface, as a fast risetime, high intensity light source for drift mobility measurements in insulating wide band gap solids. The measurable carrier transit time is limited by the laser pulse risetime to 20 nsec. The peak emissive power measured as a function of wavelength was found to have a maximum corresponding to a temperature of 104°K. The integrated peak power of the breakdown at an air/glass interface was 2.5×103 W/sr. The source has been used to measure carrier mobilities under transient space-charge-limited current conditions in materials having band gaps ranging from 2.5 to 4.0 eV. © 1968 The American Institute of Physics.
