A solid which is transparent to visible light and whose conductivity increases with temperature is formed by
metallic binding
ionic binding
covalent binding
van der Waals binding
As we have learnt,
Photo diode -
A special type of photo detector.
- wherein
By measuring the change in the conductance of the semicondutors one can measure the intensity of the optical signal
By throwing visible light, conductivity will increase. If bond breaks, bound energy of covelent bond fall in this region hence its conductivity will increase.
