Four-point measurements are carried out on a Hall bar using specially designed capacitive contacts, reproducing the transport characteristics Rxx measured using standard ohmic contacts. All Rxx measurements using various combinations of ohmic and cap

We report on non-equilibrium transport measurements as a function of Fermi-energy of two-dimensional (2D) to one-dimensional (1D) resonant tunneling transistors. The investigated samples are fabricated by means of the cleaved-edge overgrowth method t

A doping series of AlAs (001) quantum wells with Si delta-modulation doping on both sides reveals different dark and post-illumination saturation densities, as well as temperature dependent photoconductivity. The lower dark two-dimensional electron d

A quantum wire is fabricated on (001)-GaAs at the intersection of two overgrown cleaves. The wire is contacted at each end to n+ GaAs layers via two-dimensional (2D) leads. A sidegate controls the density of the wire revealing conductance quantizatio

We demonstrate a contact design that allows four-terminal magnetotransport measurements of cleaved-edge overgrown two-dimensional electron and hole systems. By lithographically patterning and etching a bulk-doped surface layer, finger-shaped leads ar

Twofold application of the well established cleaved‐edge overgrowth technique can achieve an orientation of a quantum wire parallel to the growth axis of a prior grown substrate. Hence a variation of the substrate layers directly transfers the resu

The objective of this study was to determine the absorbed radiation doses to various structures within the head and neck as a result of routine mandibular and maxillary occlusal radiography. Five projections were investigated: the anterior mandibular

A vertical pillar shadow epitaxy technique is introduced for fabricating coplanar striped or cross-hatched GaAs∕AlAs two-dimensional heterostructures, where the pattern area of each individual layer can be varied in situ. An array of vertical pilla
