PN junction characteristics and photoelectromagnetic effect in bone.
The characteristics of PN junction in bone are investigated. Collagen (N type) and apatite (P type) complex are supposed to form this junction and their behaviour for reverse and forward bias is examined. It is suggested that mucopolysaccharides play an important role in controlling junction characteristics. There is found to be generation of photocurrent in response to infrared light; while ultra-violet light produces a permanent change in its behaviour. Magnetic field is found to enhance the optical response of the junction.
