Electron-electron interaction and tunnel density of states at the Fermi level in high-density two- dimensional electron system
The zero bias anomaly (ZBA) of the tunnel conductivity are investigated in the Al/δ−GaAs tunnel structure with 2D electron concentration in δ-layer to be equal to 3.6∗10 cm−2. We find that the dip (ZBA) in the tunnel density of states near the Fermi level EF reveals logarithmic dependence on the energy ε in the range kT < ε< h̄/τ . Here ε is the energy relative to EF and τ is the elastic relaxat...
متن کاملFirst-Principles Investigation of Density of States and Electron Density in Wurtzite In0.5Ga0.5 N Alloys with GGA-PBEsol Method
In present work, we have calculated the electronic properties including density of states and electron density for GaN, InN and InxGa1-xN in wurtzite phase for x=0.5. The study is based on density functional theory with full potential linearized augmented plane wave method by generalized gradient approximation for calculating electronic properties. In this report we concluded that InxGa1-xN ba...
متن کاملThe effect of high-energy electron beam on drawn and undrawn high density polyethylene fibers
HDPE monofilaments were obtained using different extruders and drawn by post-extruder equipments. After solidification, drawn and undrawn monofilaments (draw ratio 7:1) were irradiated with 10 MeV electron beams in air at room temperature at 25, 50, 75, 100 and 125 kGy dose ranges to induce a network structure. HDPE crosslinking was studied on the basis of gel content measurements. The fibers w...
متن کاملComparing measured and calculated local density of states in a disordered two-dimensional electron system
The local density of states (LDOS) of the adsorbate induced two-dimensional electron system (2DES) on n-InAs(110) is studied by low-temperature scanning tunneling spectroscopy. In contrast to a similar 3DES, the 2DES LDOS exhibits 20 times stronger corrugations and rather irregular structures. Both results are interpreted as a consequence of weak localization. Fourier transforms of the LDOS rev...
