摘要:
A new phenomenon is reported whereby illumination (in the visible spectrum) is converted into mechanical strain (elastic deformation or mechanical vibrations) in CdS wafers with an orientation perpendicular to the crystallographic axis [001]. It is believed that the light modulates the electric field at the surface (surface barrier) and causes an elastic strain due to the converse piezoelectric effect.
