Atomic Jump Frequencies in Intermetallic Compounds Studied Using Perturbed Angular Correlation of Gamma Rays
Atomic jump frequencies were determined in a variety of intermetallic compounds through analysis of nuclear relaxation of spectra measured using the nuclear hyperfine technique, perturbed angular correlation (PAC) of gamma ...
EXCIMER LASER INTERACTION WITH ZINC OXIDE
When single crystal ZnO is exposed to 193-nm laser photons in vacuum at fluences below 100 mJ/cm
INTRINSIC DEFECTS AND SODIUM ACCEPTORS DOPING IN ZNO
Zinc oxide (ZnO), with a direct band gap of 3.37 eV at room temperature, attracts considerable attention because of its promising applications for blue-UV light-emitting diodes, diode lasers and spintronics.A problem with ...
EFFECT OF SILICON, TANTALUM AND TUNGSTEN DOPING AND POLARIZATION ON BIOACTIVITY OF HYDROXYAPATITE
Hydroxyapatite (HAp) ceramics has important applications as bone graft because of the structural and compositional similarities with bone tissue. However, inferior osteogenic capacity to bone and poor mechanical properties ...
Photomechanical actuator device based on Disperse Red 1 doped poly(methyl methacrylate) optical fiber
The photomechanical effect is the phenomenon involving any mechanical property change of a material induced by light exposure. Photomechanical devices can be built with superior performance over traditional devices and ...
Application-driven studies of photomechanical materials
Deep brain stimulation therapy is a well-established medical procedure with well-documented benefits, but this procedure would be enhanced by a flexible therapy device that could bend when photoactivated. To this end, two ...
Persistant Photoconductivity of Strontium Titanate
Strontium titanate (SrTiO$_3$) is a transparent conducting oxide with a range of interesting properties, including a large, temperature-dependent dielectric constant and superconductivity at low temperatures. It has a wide ...
Electrical and Optoelectronic Properties of Two-Dimensional Materials
Electrical and optoelectronic properties of bulk semiconductor materials have been extensively explored in last century. However, when reduced to one-dimensional and two-dimensional, many semiconductors start to show unique ...
Pressure-Induced Phase Transitions of Indium Selenide
In2Se3 has potential as a phase-change material for memory applications. Understand- ing its phase diagram is important to achieve controlled switching between phases. Pressure-dependent phase transitions of In2Se3 bulk ...
CVD GROWTH AND RAMAN SPECTROSCOPY STUDY OF VAN DER WAALS IN2SE3
Using micro-Raman spectroscopy and finite-element simulations, we determine the in-plane thermal conductivity of suspended two-dimensional single-crystal In2Se3 grown by chemical vapor deposition. The thermal conductivity ...
