The Van Hove singularity (VHS) provides a paradigm for the study of the role of peaks in the density of states (dos) on electronic properties. More importantly, it appears to play a major role in the physics of the high-Tc superconductors, particularly since recent photoemission studies have found t...

The observed increase of superconducting transition temperature (T(c)) with the number of copper oxide planes continues in the four-[CuO(2)](-2) layer (single TI layer) oxide superconductor, which has been prepared with > 80% purity and was magnetically aligned for crystallographic identification. A...

In the present paper, density functional theory (DFT) based first‐principles methods are applied to investigate the mechanical and bonding properties of the newly synthesized T 2 phase superconductor Ta 5 GeB 2 for the first time. The calculated lattice constants are in reasonable agreement with the...

Abstract Antiferromagnets have been generating intense interest in the spintronics community, owing to their intrinsic appealing properties like zero stray field and ultrafast spin dynamics. While the control of antiferromagnetic (AFM) orders has been realized by various means, applicably appreciate...

Thermal characterizations and modeling have been carried out on a 0.15 μm× (4×50) μm gate GaN-/SiC-based high-electron-mobility transistor varying the temperature from -40 °C to 150 °C and the frequency up to 50 GHz using on-wafer measurements. The thermal behavior of the dc parameters along with th...

We present one nonlinear and one linearized numerical schemes for the nonlinear epitaxial growth model without slope selection. Both schemes are proved to be uniquely solvable and convergent with the convergence rate of order two in a discrete <inline-formula content-type="math/mathml"> <mml:math xm...

A general review on cuprate based superconducting materials has been made. The special features of cuprate based high-temperature superconductors have been explained from the material side and the physical properties side. The present statuses on applications of cuprate based high-temperature superc...

For the commercial implementation of GaN-based high electron mobility transistor (HEMT) and GaN-based pseudomorphic HEMT (pHEMT), the temperature dependency of the two-dimensional electron gas (2DEG) is crucial. Herein, the temperature dependency of 2DEG for AlGaN/GaN HEMT and AlGaN/InGaN/GaN pHEMT ...

Using molecular dynamics simulations, it is shown that a carbon nanotube (CNT) suspended in water and subjected to a rotating electric field of proper magnitude and angular speed can be rotated with the aid of water dipole orientations. Based on this principle, a rotational nanomotor structure is de...
