Thermally Stimulated Capacitance (TSCAP) in p-n Junctions

Abstract: High-frequency small-signal capacitances of semiconductor junction vs temperature, from the initial conditions of filled and emptied traps in the junction depletion region, are used to determine the trap concentration and the thermal activation energies of trapped electrons and holes. Illustrations are given for silicon N + P diodes doped with gold impurity or irradiated with 1-MeV electrons, showing the room-temperature annealing for the latter.

“…4 TSC and TSCAP measurements are compared. 24 In this case the sample is a n + p Si diode doped with Au. As the n-type region has a very high carrier concentration (hence the designation is n + ), so the depletion region spreads predominantly into the p-region and the experiment explores the properties of traps in the p-region which in this case are hole traps.…”

“…C b (T) = = const; C t -емкость донорных центров с глубокими уровнями; R t -сопротивление перезарядке глубо-ких уровней; C 0 -емкость входного конденсатора, создающего режим инжекции в ОПЗ малого заряда Q 0 = UC 0 ; U -амплитуда входного напряжения ме-андра. Постоянная времени перезарядки глубоких центров R t C t выражается формулой (2).…”
