12.5. Match the eect with the denition.
1. Whenanoptical eld is applied to a
dielectric material, a material polarization
develops inthe material.
2. Whenanoptical eld is applied to a
semiconductor junction, a voltage develops
across the junction.
3. Whena current passes through a uniform
material which has a temperature gradient,
heating or cooling will occur
4. Whena mechanical stress is applied to a
dielectric material, a material polarization
develops inthe material.
5. Whenthe dierent sides of a junctionare
held at dierent temperatures, a voltage
develops across the junction.
6. When an external magnetic eld is
applied across a conductor or semiconductor
with current owing through it, a charge
builds up perpendicular to the current and
external magnetic eld.
