Local electronic imaging using a scanning microwave impedance microscope (MIM) is performed on as‐grown CdZnTe bulk crystals at room temperature. Well‐defined Te‐rich secondary phase (SP) particles embedded in CdZnTe crystals are clearly observed in the MIM images. The high contrast observed via MIM is attributed to the discrepance between the dielectric response and conductivity of Te‐SP particles...
In this paper, we present the theoretical calculations of the dispersion curves of Lamb mode waves in one-dimensional magnetoelastic phononic crystal (PC) plates by using the finite element method (FEM) and the plane wave expansion (PWE) method. The effects of filling fraction and plate thickness to lattice pitch ratio on the first band gap (FBG) are analyzed under different magnetic boundary conditions...
Research on the high-intensity laser frequency doubling in KDP crystal with a temperature distribution for typeIangle-phase matching has been carried out by the use of a split-step fast Fourier transform algorithm and a fourth-order Runge-Kutta(R-K) integrator method. Special attention has been paid on the influences of the temperature distribution in the crystal owing to laser energy's absorption...
