CONDENSED MATTER PHYSICS: Conduction Electrons in an Intrinsic Semiconductor, Thermistors, LDRs and Conduction in a Doped Semiconductor.
Suppose an electron needs energy E to escape from its surroundings, and that this energy is supplied thermally. The temperature T (in kelvin) multiplied by the Boltzmann constant k indicates the amount
OSCILLATIONS AND MECHANICAL WAVES: Displacement, Velocity and Acceleration of Simple Harmonic Motion.
In simple harmonic motion, the displacement varies sinusoidally with time β and this is a lot more complicated than if displacement were linear with time. The figure below shows the displacement for an
