Surface Fermi level tuning in thin epitaxial Bi<i>y</i>Sb2−<i>y</i>Te3−<i>x</i>Se<i>x</i>/Si(111) films
The effects of chemical treatment and aging of BiySb2−yTe3−xSex 3D topological insulator (TI) thin films on the surface electronic structure, morphology, and transport properties have been studied. Th...
Structural, electronic, and superconducting properties of MBE-grown tantalum nitride films on c-plane sapphire
Two single crystal phases of tantalum nitride were stabilized on c-plane sapphire using molecular beam epitaxy. The phases were identified to be δ-TaN with a rock salt cubic structure and γ-Ta2N with...
Integrated fiber supercapacitor coils enabling wireless charging and passive voltage monitoring
Fiber supercapacitors (FSCs) have attracted extensive research interest in the field of flexible electronics and wearable devices. This paper presents integrated FSC coils capable of inducing charging...
Small surface potential fluctuation near the valence band edge at nitrided 4H-SiC(0001)/SiO2 interfaces
Interface states near the valence band edge at a nitrided 4H-SiC(0001)/SiO2 interface were investigated by the conductance, C–ψS, and high-low methods. Consistent energy distribution of the interface...
Deducing safety margin from boiling crisis for arbitrary solid/fluid combinations through the universality of temperature fluctuations
Despite decades of research, boiling heat transfer continues to be represented using dimensional quantities (heat flux vs wall superheat relative to liquid saturation temperature). Here, we show that...
The impact of defect evolution on the electrical performance of AlGaN/GaN HEMT after 14-MeV neutron irradiation
In this work, we study the electrical performance of AlGaN/GaN high-electron-mobility transistors following irradiation with 14 MeV neutrons at fluences of 3 × 1012, 7.4 × 1012, 1.2 × 1013, and 1.0 × ...
Impulsive excitation of squeezed phonons in single crystal germanium by an x-ray laser
In this Letter, we present the experimental observation of squeezed phonon generation in semiconductor germanium (Ge) induced by x-ray excitation. Prior x-ray pump, x-ray probe studies reported cohere...
