چکیده

We derive the ratio of transport and single-particle relaxation times in threeand two-dimensional electron gases due to scattering from charged dislocations in semiconductors. The results are compared to the respective relaxation times due to randomly placed charged impurities. We find that the ratio is larger than the case of ionized impurity scattering in both threeand two-dimensional electron transport.

Dislocation scattering in a two dimensional electron gas

A theory of scattering by charged dislocation lines in a two-dimensional electron gas (2DEG) is developed. The theory is directed towards understanding transport in AlGaN/GaN high-electron-mobility transistors (HEMT), which have a large number of line dislocations piercing through the 2DEG. The scattering time due to dislocations is derived for a 2DEG in closed form. This work identifies disloc...

Dislocation Structure and Mobility in Hcp Rare-Gas Solids: Quantum versus Classical

We study the structural and mobility properties of edge dislocations in rare-gas crystals with the hexagonal close-packed (hcp) structure by using classical simulation techniques. Our results are discussed in the light of recent experimental and theoretical studies on hcp 4He, an archetypal quantum crystal. According to our simulations classical hcp rare-gas crystals present a strong tendency t...

Quantum Effects in the Conductivity of a Quasi 2D Electron Gas

We consider the role of the third dimension in the conductivity of a quasi 2D electron gas. It is demonstrated that, if the transverse correlation radius of the scattering potential is smaller than the width of the channel, i.e. the width of the transverse electron density distribution, then scattering to higher levels of the confinement potential becomes important and the current flow profile ...

Effect of charged dislocation scattering on electrical and electrothermal transport in n-type InN

Temperature-dependent thermopower and Hall-effect measurements, combined with model calculations including all of the relevant elasticand inelastic-scattering mechanisms, are used to quantify the role of charged line defects on electron transport in n-type InN films grown by molecular-beam epitaxy. Films with electron concentrations between 4 × 1017 and 5 × 1019 cm−3 were investigated. Charged ...

Phohon Drag in Disordered Films and Structures

Quantum transport in disordered systems has been studied for many years, yet many open problems remain. One focus of these investigations is the interference of inelastic electron scattering due to electron-phonon interaction and elastic electron scattering due to impurities, boundaries and defects. Electron-phonon interaction determines the electron energy loss rate and also manifests itself i...
