Optical absorption and refractive index of evaporated cadmium arsenide thin films in infrared region / Mahadzir Hj. Din

Measurements of transmission in the infrared showed interference maxima and minima from which the refractive index nr and the absorption coefficient a were determined. Values of refractive index of 5.3 and 5.6 were determined for films deposited under different conditions, and are reasonably consis...

The value of the absorption coefficient, a calculated was in the range of 10* (cm1) for film thickness 1.5 mm and substrate temperature, Ts at 300 K and it increases to in the range of 10s (cm1) for film thickness 0.46//m and substrate temperature 453 K.
