Highly aligned crystalline In–Ga–O thin films demonstrate extremely high field-effect mobility and remarkable thermal stability at temperatures of 700 °C (96.0 → 128.2 cm2 V−1s−1). Also, its excellent step coverage, compositional uniformity in a 40:1 aspect ratio structure, and superior crystal growth in vertical structures make it a promising candidate...

Composites made of semiconducting carbon nanotubes and p-type polymers, when adequately doped with molecular dopants, can exhibit highly delocalized charge carrier transport, showing high thermoelectric performances. The efficient charge delocalization is enabled by the reduced coulombic binding energy at high carrier concentration and the small transport...

Ca3(PO4)2 film with superior insulating properties and biocompatibility is introduced as an insulating layer material for the first time. Its electrical insulation, stability, and optical transparency are thoroughly evaluated. A bio-friendly low-temperature supercritical fluid desorption technique is developed to further optimize the insulation performance....

AlGaN-based DUV FP laser diodes find that the optical field profiles can be strongly affected by the refractive index profiles in the p-type and the n-type regions. An asymmetrical optical field is required, which enables the reduced internal optical loss and more favors the simulated recombination in the active region. This in turn reduces the electron...

The impact of the gate bias on the charge carrier mobility is investigated by the microwave resonance technique. Although the microwave resonance technique is fully non-contact measurement, the nonlinearity is clearly observed. Based on the simulation and assessment, it is concluded that the surface disorder is the inherent origin of the nonlinearity...

The angular dependence of Hall-humps is investigated in various oxide heterostructures by assigning divergence exponents to Hall-humps. It can distinguish between the Geometrical Hall Effect by non-coplanar textures and the Anomalous Hall Effect by collinear magnetization. A linear scaling is found between the divergence exponent and the collinear...
