High quality berylium doped InAs layer grown by MBE on GaAs substrate has been examined via magnetotransport measurements and high resolution quantitative mobility spectrum analysis in the range from 5 to 300 K and up to 15 T magnetic field. The layer homogenity and dopant concentration has been proofed via HR-SIMS. The results shew four channel conductivity and essential splitting of the most populated holelike channel below 55 K. The multilayer model concluded from the QMSA results has been… Expand

Thermoelectric evaluation of the dopant density of p-type InAs
Thermoelectric measurements were performed on p-type InAs thin films grown by metalorganic vapor phase epitaxy. The measured Seebeck coefficient displayed an anomalous temperature dependence due toExpand
Heavy and light hole transport in nominally undoped GaSb substrates
In this work, we report results of a study of electronic transport in nominally undoped p-type GaSb wafers typically employed as substrate material for the epitaxial growth of InAs/GaInSb type-IIExpand
Structural and optical characterization of the high quality Be-doped InAs epitaxial layer grown on GaAs substrate
The highly Be-doped InAs layer has been grown on semi-insulating GaAs (100) substrate by Molecular Beam Epitaxy. Very good quality of the layer has been attested by high resolution scanning electronExpand
Transport coefficients of InAs epilayers
Heteroepitaxially grown single‐crystal InAs layers exhibit anomalies in the magnetic field dependence of their Hall coefficients, their magnetoresistance, and the temperature dependence of theirExpand

Dependence of the Mg-related acceptor ionization energy with the acceptor concentration in p-type GaN layers grown by molecular beam epitaxy
Hall effect and capacitance-voltage C(V) measurements were performed on p-type GaN:Mg layers grown on GaN templates by molecular beam epitaxy with a high range of Mg-doping concentrations. The freeExpand
Statistics of the Mg acceptor in GaN in the band model
The discrete energy level is not appropriate for free-hole statistics of the heavy Mg doping of GaN. The band model assumes the broad acceptor band centred at 0.20 eV above the valence zone. ItsExpand
Scaling of the breakdown in the impurity band of doped GaAs/AlGaAs quantum well demonstrating virtual Anderson transition
Abstract We observed breakdown behavior for highly doped and low compensated p-type layers located within the central part of GaAs/AlGaAs quantum wells at rather small values of the applied bias.Expand
Carrier concentration and transport in Be-doped InAsSb for infrared sensing applications
Accurate p-type doping of the active region in III-V infrared detectors is essential for optimizing the detector design and overall performance. While most III-V detector absorbers are n-type (e.g.,Expand

Abstract A comparative survey of known experimental and theoretical values of heavy-hole and electron effective mass in GaAs, InAs, and A1As is presented in this work. Recommended room-temperatureExpand
