Values of absorption constant covering the range 1 cm−1 to 104 cm−1 have been derived from transmission measurements made on single‐crystal gallium arsenide. The absorption edge is very steep up to ∼4000 cm−1, where there is a knee beyond which the absorption increases relatively slowly with photon energy. The energy bands have been calculated using Kane's theory. From these a theoretical absorption curve has been obtained which shows very good agreement with the experimental data.Using semi… CONTINUE READING
