Size-dependent photoconductivity in MBE-grown GaN-nanowires.

We report on electrical transport in the dark and under ultraviolet (UV) illumination through GaN nanowhiskers grown by molecular beam epitaxy (MBE), which is sensitively dependent on the column diameter. This new effect is quantitatively described by a size dependent surface recombination mechanism. The essential ingredient for the interpretation of this effect is a diameter dependent recombin...

Advanced Strain Compensation in MBE-Grown Semiconductor Disk Lasers

Nowadays semiconductor disk lasers are of great importance in virtue of their high output power. In fact, it is common to fabricate devices having an output power of several watts [1, 2]. Furthermore, the free access of the resonator allows intracavity SHG (second harmonic generation) using nonlinear crystals. In this way, the range of emission wavelengths that can be realized using different c...

Spin Lifetime Measurements in MBE-Grown GaAs Epilayers

Electron spin relaxation times in excess of the localized limit have been measured in MBE n-GaAs layers, with the times depending on the doping concentration. We have optically oriented the electrons in the samples, and measured spin lifetimes via luminescence depolarization in a transverse magnetic field (Hanle effect). The lifetimes thus obtained were 14 and 26 ns for samples nominally doped ...

Integral Quantum Hall Effect in Mbe Grown Thin Films

We aim to study Integral Quantum Hall Effect in MBE-grown thin films like Graphene,Bismuth,GaAs and FeSiO2.We aim to look at how the quantum size effects dominate the electrical transport properties like the resistivity, hall coefficient, magnetoresistance coefficient and low-frequency electrical noise. We are also interested to look at the measurements on the MBE-grown AlGaAs/GaAs heterojuncti...

Temperature-Dependent X-ray Diffraction Measurements of Infrared Superlattices Grown by MBE

Strained-layer superlattices (SLSs) are an active research topic in the molecular beam epitaxy (MBE) and infrared focal plane array communities. These structures undergo a >500 K temperature change between deposition and operation. As a result, the lattice constants of the substrate and superlattice are expected to change by approximately 0.3%, and at approximately the same rate. However, we pr...
