Carrier Dynamics in Energy Wavevector Space
In an E–k diagram, the slope of the energy vs. wavevector curve represents:
Which physical quantity is directly proportional to the wavevector k in semiconductors?
In a semiconductor, the bandgap energy (Eg) refers to:
A flatter E–k curve around the conduction band minimum indicates:
Which relation connects effective mass (m*) with the curvature of the E–k diagram?
Among Si, GaAs, and Ge, which has the smallest bandgap energy at room temperature?
If the curvature of the conduction band increases, what happens to the effective mass?
For a semiconductor with Eg = 1.2 eV, what is the approximate photon wavelength corresponding to this bandgap?
What happens to group velocity when the E–k curve becomes very steep near the conduction band edge?
