Nonequilibrium carrier recombination in highly excited epitaxial layers of 4HSiC and free standing 3CSiC was analyzed numerically and studied experimentally by the time-resolved free carrier absorption (FCA) technique. The measurement setup combined interband carrier excitation by a picosecond laser ... [J. Appl. Phys. 108, 023705 (2010)] published Tue Jul 27, 2010.

The crystallization speed (v) of the amorphous (InTe)(GeTe) (x=0.1, 0.3, and 0.5) films and their thermal, optical, and electrical behaviors were investigated by using a nanopulse scanner (wavelength=658 nm, laser beam diameter <2 [mu]m), x-ray diffraction, a four-point probe, and a UV-vis-IR spec ...

Remote sensing of ground vibration is a key tool in the detection of shallowly buried objects, such as land mines. Millimeter wave systems show promise for replacing laser Doppler vibrometers as the key sensing technology on the grounds of reduced cost and because they provide a larger (10 cm versus ... [J. Appl. Phys. 108, 024902 (2010)] published Tue Jul 20, 2010.

Ultrafast dynamics of genuine magneto-optical recording across ferrimagnetic compensation points is demonstrated in GdFeCo films using time-resolved polar Kerr spectroscopy combined with a laser-synchronized sinusoidal alternating magnetic field which can reinitialize irreversible initial magnetizat ...

In this paper, laser annealing is used to produce metal (Ag) nanoparticles as etching catalyst on a silicon surface, which enables controllable fabrication of large-scale nanohole array surface texturing without using a mask. Semispherical Ag nanoparticles with variable size and distribution are ach ... [J. Appl. Phys. 108, 024301 (2010)] published Fri Jul 16, 2010.

Laser dynamic forming (LDF) is a novel high energy rate microfabrication technique, which makes use of the shock pressure induced by laser to generate dynamic high strain rate three dimensional (3D) forming of thin films. In LDF process, a high shock pressure accelerates the workpiece to a high velo ... [J. Appl. Phys. 108, 013107 (2010)] published Tue Jul 13, 2010.

Photocurrent (PC) spectra representing the in-plane absorption of the quantum-wells (QWs) in diode lasers are monitored. Spectra from pristine and systematically aged devices are analyzed and aging-induced changes are explained within the frame of rate-equation models for nonequilibrium carriers. We ... [J. Appl.

In order to further understand the pulsed-laser melting (PLM) of Mn and N implanted GaAs, which we have used to synthesize thin films of the ferromagnetic semiconductor GaMnAs and the highly mismatched alloy GaNAs, we have simulated PLM of amorphous (a-) and crystalline (c-) GaAs. We present a numer ... [J. Appl. Phys. 108, 013508 (2010)] published Tue Jul 6, 2010.

Annealing-induced changes in structural and magnetic property of ZnCoO thin film prepared at a low oxygen pressure by pulsed laser deposition have been studied with x-ray absorption fine structure, x-ray diffraction, and magnetization measurement. Intrinsic ferromagnetism at room temperature is obse ... [J. Appl. Phys. 108, 013901 (2010)] published Fri Jul 2, 2010.

Recently we found epitaxial Fe-deficient yttrium iron garnet YFeO (YIG) films pulsed laser deposited onto the (111) and (001) face of GdGaO single crystal experience, respectively, strong rhombohedral and tetragonal distortions and possess unusual magnetic anisotropy. Using the crystal field theory, ... [J. Appl. Phys. 108, 013902 (2010)] published Fri Jul 2, 2010.
