熱刺激電流曲線に高感度をもつ漸近解法I法の提案と新しい解析への応用

抄録

The asymptotic estimation I method which enables one to evaluate the energy depth of carrier trap from the 1st order thermally stimulated current (TSC) curve is proposed. This method uses three fundamental elements, the peak temperature and two coordinates. Two coordinates can be used in two ways, only one coordinates are shifted with another fixed coordinates and coupled coordinates with constant temperature interval ΔT are moved on the TSC curve. The I method with small ΔT has very high sensitivity to the TSC curve fluctuation. This fine characteristic enables one to detect the peak temperature involved in the obscure case whether the objective TSC curve is single or not, and it leads to separating their curves. Additionally, the I method can detect background noise involved in the TSC data and remove it to a sufficient extent.
