Here, we report on how the energy band diagram of a nanostructured semiconductor- metal interface aligns in accordance with semiconductor morphology. Electrochemically, titanium metal is anodized to form titanium dioxide nanotubes, which forms a junction with the free Ti substrate and this junction ...
When Φm> Φn, a Schottky junction is formed when the n-type (or p-type) semiconductor is in contact with the metal. The Schottky junction is used to create Schottky barrier diodes. The following shows the band diagram of a Schottky junction formed by an n-type...
Schematic band-diagram of a Schottky-junction for (a) reverse bias and (b) forward bias voltages applied on Al-Schottky contact. The green lines at the NV charge transition levels indicate the NV-layer region. For reverse bias voltages applied on Schottky contact the Fermi-level EF is pushed...
(b) Schematic lateral band diagram of the in-plane Al-Schottky junction, i.e. Al is in contact with the H-terminated diamond surface (x-axis as depicted in Fig. 2a). A Schottky barrier for holes and a hole depletion region at the edge of Al contact is induced. In this case the...
(d) Band diagram of device (c) under high bias: the depletion layer of the reverse biased junction A extends and meets that of B (forward biased junction) so that the whole semiconductor between the electrodes is depleted. Often a pair of Schottky photodiodes in a so-called interdigital ...
The conduction band electrons orfree electronsthat are crossing the junction will provide extra electrons to the atoms in the metal. As a result, the atoms at the metal junction gains extra electrons and the atoms at the n-side junction lose electrons. ...
2.1 Barrier Height, Interface States, Junction Formation, and Equilibrium Properties A Schottky barrier is similar to a pn junction or heterojunction in which the doping on one side increases to the point where it becomes metallic. The band diagram of an ideal metal on n-type semiconductor Schott...

(SMS) structure and its band diagram. The SMS MBT employs thermionic emission rather than tunneling injection of hot carriers into the base because the Schottky junction has smaller emitter-to-base barrier height than the MIM structure. Early MBTs have been plagued by two major problems, which ...
The operation of the SLG-CNTF Schottky junction IR photodetector can be interpreted by the energy band diagram illustrated in Fig. 7. When metallic SLG was transferred onto the CNTF, a built-in potential in CNTF near the interface (the depletion region) was formed due to the difference in wo...
