Influence of substrate surface defects on the homoepitaxial growth of GaN (0001) by metalorganic vapor phase epitaxy
TL;DR: In this article, the surface morphology of homoepitaxial GaN (0001) grown by metalorganic vapor phase epitaxy was studied and the step pattern developed to a wavy surface with a strip-like feature along the [11 ($) over bar0] direction during the subsequent growth of a thick n-GaN layer.
Journal ArticleDOI
Thermodynamic properties calculation for MgO–SiO2 liquids using both empirical and first-principles molecular simulations
TL;DR: It is found that first-principles simulation modified the thermodynamic properties of silicate melts, and led to positive enthalpy of mixing at high SiO(2) concentrations and negative ones at lowSiO( 2) concentrations.
Journal ArticleDOI
Flexible breathable photothermal-therapy epidermic sensor with MXene for ultrasensitive wearable human-machine interaction
TL;DR: In this paper , a flexible wearable epidermic sensor is fabricated by delicately assembling conductive MXene nanosheets and silver nanowires (AgNWs) onto electrospun elastomeric substrates for ultra-sensitive sensing and on-demand photothermal therapy.
Journal ArticleDOI
Suppression of optical field leakage in GaN-based green laser diode using graded-indium n-InxGa1-xN lower waveguide

TL;DR: In this article, a graded-indium composition n-InxGa1-xN lower waveguide (LWG) structure is proposed which should be more feasible to grow with high material quality and at the same time can effectively reduce the optical field leakage in GaN-based green laser diodes.

High dielectric constant and low-modulus dielectric elastomer material and preparation method thereof
TL;DR: In this paper, a high dielectric constant liquid disperses in a rubber substrate in the form of drops or molecules horizontally, so as to obviously reduce the modulus of the dielectrics elastomer and improve the Dielectric constants of the elastomers.
