The effects of the donor concentration and the compensation degree of N-InSb material on the performance of InSb electron bolometer

It is shown by Hall measurements that the hot electron nonlinear T-V characteristics of a-InSb materials critically depend on their compensation degree K and excess donor concentration no. The InSb electron bolometer was fabricated by using a-InSb ma terials with different X and no. The experimental data show that the NEF of the detector made of highly compensated material is better than that made of low compensa tion material.
