  2. Band diagram - Wikipedia

    en.wikipedia.org/wiki/Band_diagram

    Band diagram for Schottky barrier at equilibrium Band diagram for semiconductor heterojunction at equilibrium. In solid-state physics of semiconductors, a band diagram is a diagram plotting various key electron energy levels (Fermi level and nearby energy band edges) as a function of some spatial dimension, which is often denoted x.

    Energy band diagram of a simple bipolar junction transistor under equilibrium showing electron energy versus position. The depletion regions of the emitter-base and base-collector junctions are marked. <math>E_c</math> is the conduction band

  5. Band bending - Wikipedia

    en.wikipedia.org/wiki/Band_bending

    Band bending can be induced by several types of contact. In this section metal-semiconductor contact, surface state, applied bias and adsorption induced band bending are discussed. Figure 1: Energy band diagrams of the surface contact between metals and n-type semiconductors.

    Cross section of a GaAs/AlGaAs/InGaAs pHEMT Band diagram of GaAs/AlGaAs heterojunction-based HEMT, at equilibrium.. A high-electron-mobility transistor (HEMT or HEM FET), also known as heterostructure FET (HFET) or modulation-doped FET (MODFET), is a field-effect transistor incorporating a junction between two materials with different band gaps (i.e. a heterojunction) as the channel instead of ...

  8. Schottky barrier - Wikipedia

    en.wikipedia.org/wiki/Schottky_barrier

    Band diagram for n-type semiconductor Schottky barrier at zero bias (equilibrium) with graphical definition of the Schottky barrier height, Φ B, as the difference between the interfacial conduction band edge E C and Fermi level E F. [For a p-type Schottky barrier, Φ B is the difference between E F and the valence band edge E V.]

  9. Heterojunction - Wikipedia

    en.wikipedia.org/wiki/Heterojunction

    Band diagram for straddling gap, n-n semiconductor heterojunction at equilibrium. The behaviour of a semiconductor junction depends crucially on the alignment of the energy bands at the interface. Semiconductor interfaces can be organized into three types of heterojunctions: straddling gap (type I), staggered gap (type II) or broken gap (type ...
