A simple, fast, and reliable characterization of thermal properties method to determine junction temperature (Tj) in high power GaN-based light emitting diodes (LED) was presented in this study. Thermal characteristics of high power light-emitting-diode have been analyzed by using a three-dimensional thermal conduction model. Maximum operation temperature has also been calculated. The induced thermal...
Raman spectroscopy is used to measure the junction temperature of a Cree SiC MESFET as a function of the ambient temperature and DC power. The carrier temperature, which is approximately equal to the ambient temperature, is varied from 25degC to 450degC, and the transistor is biased with VDS=10 V and IDS of 50 mA and 100 mA. It is shown that the junction temperature is approximately 52 and 100degC...
CdS/CdTe/Te heterojunction have been studied by capacitance-voltage measurements over the temperature range 293 K-393 K. The potential of diffusion, profile of the ionized-charge concentration in the space charge region of heterojunction and its thickness are derived from the heterojunction capacitance measured at different bias voltages. The charge carrier concentrations calculated from (S/C)2 =...
