The response of the ensemble in situations where this steady-state or quasi-static analysis is inappropriate is called the transient dynamic response (TDR). Describing carrier transport in the TDR regime is the central topic of this chapter.

by summarizing the thermodynamic properties of quantum well conduction and valence subbands under high-level injection. This allows us to relate the electron and hole quasi-Fermi levels to the injected carrier concentration, and thereby determine the occupation probabilities of the electron and hole

on of the relationship between the nature of the eigenstates of an electron in a rigid noncrystalline solid and its transport properties is addressed. It is pointed out that the absence or presence of a finite-temperature thermally activated mobility does not necessarily follow from the electronic s

When the forcing function varies slowly on the scale of the time constants, it is common to use quasi-static analysis techniques in which the instantaneous time-varying response is modeled by using the steady-state response of the system to a constant

Although the neutron flux impinging upon a sample in a neutron instrument is several orders of magnitude less than photon flux available in X-ray sources, the favorable scattering properties of neutrons as compared to X-rays more than compensates for the lack of intensity.
