چکیده

The inherently complex chemical and crystallographic nature of oxide materials has suppressed the purities achievable in laboratory environments, obscuring the rich physical degrees of freedom these systems host. In this manuscript we provide a systematic approach to defect identification and management in oxide molecular beam epitaxy grown MgZnO/ZnO heterostructures which host two-dimensional electron systems. We achieve samples displaying electron mobilities in excess of 1 × 10(6) cm(2)/Vs. This data set for the MgZnO/ZnO system firmly establishes that the crystalline quality has become comparable to traditional semiconductor materials.

Observation of anomalous Hall effect in a non-magnetic two-dimensional electron system

Anomalous Hall effect, a manifestation of Hall effect occurring in systems without time-reversal symmetry, has been mostly observed in ferromagnetically ordered materials. However, its realization in high-mobility two-dimensional electron system remains elusive, as the incorporation of magnetic moments deteriorates the device performance compared to non-doped structure. Here we observe systemat...

Equations of state for ZnO and MgZnO by high pressure x-ray diffraction

MgZnO alloys are potentially important semiconductors for UV optoelectronics and other applications. Since device heterostructures are under significant strain, it is important to determine the elastic properties of these materials, in the bulk and nanoscale. In this work, the equations of state were obtained for ZnO and MgxZn1 xO alloys under hydrostatic pressure, using x-ray diffraction. The ...

Dependence of Electrical Properties of InAlN/GaN and InAlN/AlGaN/GaN Heterostructures FETs on the AlN Interlayer Thickness

We investigated the influence of the thickness of the AlN interlayer for InAlN/GaN and InAlN/AlGaN/GaN heterostructures. The AlN thickness strongly affects the surface morphology and electron mobility of the InAlN/GaN structures. The rms roughness of the surface increases from 0.35 to 1.2 nm with increasing AlN thickness from 0 to 1.5 nm. Large pits are generated when the AlN is thicker than 1 ...
