Proceedings IEEE/Cornell Conference on Advanced Concepts in High Speed Semiconductor Devices and Circuits.
Epitaxial Si/ZnS/Si heterostructures were grown for the purpose of developing silicon-based quantum devices. An arsenic passivation technique was used on silicon surfaces for the growth of ZnS. A two-step growth method was developed for the epitaxial
Experiments were performed to determine the effect of radiation on quantum devices. The devices included resonant tunneling devices and two-dimensional electron gas devices. None of the devices were radiation-hardened prior to testing. The radiation

We carried out magnetotransport measurements and scaling analysis to report on a new magnetic-field-induced metal-insulator transition in two dimensions, where the separatrix between insulating and conducting states appears at a critical magnetic fie

Nanoscale gated quantum wires in GaAs MODFET material with the conduction channel and gates in the plane of the 2DEG have been fabricated and studied. Electron beam lithography was used for mask definition followed by flood exposure to low energy arg

Giant magnetoresistance was observed in a disordered two‐dimensional electron system in a variable‐range hopping regime. The possibility of utilizing the phenomenon as a magnetic field sensor was demonstrated by the detection of trapped vortices

We present a systematic study of the low‐temperature magnetotransport properties of modulation‐doped GaAs heterostructures to examine the device isolation mechanism in a low‐energy (150 eV) Ar+ ion exposure process. Measurements were carried ou

The fabrication of a nanoscale gated quantum wire in a GaAs modulation doped field effect transistor substrate is described. Both the wire conduction channel, with a 110 nm physical width, and the gates were patterned into the two‐dimensional elect

In order to determine the electrical isolation mechanism of low energy ions impinging on GaAs heterostructures, a systematic magnetotransport study was performed on the two‐dimensional electron gas (2DEG) of a GaAs modulation doped heterostructure.

Nine Spanish olive oils, including three each of virgin (pressed oil), refined virgin, and B-residue (solvent-extracted pomace oil) oils from different commercial sources, have been analyzed for their unsaponifiable matter (USM). Four sterolic fracti
