Abstract

PURPOSE:To provide sensitivity from the visible light region to the infrared region to a receptor and relieve the optical fatigue by forming an Se layer and an Se-Te layer on a substrate in order and making the resistance of a region of each of the layers opposite to the substrate to positive holes higher than that of the other region. CONSTITUTION:On substrate 1 of Al or the like, Se having 99.99% purity is vacuum-deposite at 65-75 deg.C substrate temp., and after releasing substrate 1 from the vacuum and feeding O2, Se layer 2 is heat-treated to form region 20 with higher resistance. On region 20 Se-Te is vacuum-deposited at 35-50 deg.C substrate temp. to form Se-Te layer 3, and layer 3 is heat-treated at 65-75 deg.C in air to form region 30 with higher resistance. Se layer 2 has about 40mum thickness, and Se-Te layer 3 is <=1/4 time as thick as layer 2. Layer 3 contains 6-25 atomic% Te. Thus, a receptor having sensitivity even in the infrared region and enabling the use of semiconductor laser as a light source is obtd. The receptor has high dark resistance and undergoes slight optical fatigue.
