Composition dependence and random alloy effects for Cu and Fe in the semiconductor alloy AlGaAs
Our investigations of one iron- and two copper-related deep acceptor levels in the semiconductor alloy AlGaAs show that the opticalthreshold energies have the same linear composition dependence for all three l...

Laser-induced internal cracks in LiF single crystals
Internal cracks were generated in LiF single crystals using a focused short-pulse laser. The laser-induced fracture region is composed of a central damage zone of fragmentation and three orthogonal penny-like ...

Artificial regeneration of Korean spruce in northeast China
Korean spruce (Picea koraiensis Nakai) has been included as a Chinese regeneration species since the 1960′s. In the 1970′s it became one of the four most important species in the northeast forest region of China....

Studies of recombination X-ray-laser gain and gain-medium uniformity
The time evolution of the uniformity of the line-shaped X-ray-laser gain medium and the spatial characteristics of the recombination X-ray-laser gains of the Li-like ions are studied using long (∼900 ps) and s...

Novel nicotinic receptor ligands
Few agents (agonists) bind at [3H]nicotine-labeled nicotine receptors with an affinity comparable to that of nicotine. We initially approached this problem by undertaking a systematic structure-affinity study to ...

Apoptosis and Tumor Invasion in Hormone-Dependent Cancers
Accumulating evidence demonstrates that apoptosis is not a single phenomenon, but a series of morphologically and biochemically related processes (1, 2). Cell death of lymphocytes and other cells of reticulo-e...

Effect of Pb Excess Content on Microstructure and Electrical Properties of Sol Gel Derived PZT Thin Films
Lead zirconate titanate (PZT) thin films were fabricated by a three-step heat-treatment process which involves the addition of -10, 0 and 10 mol% excess Pb to the starting solution and spin coating onto Pt/Ti/SiO

Quantum-dot superluminescent diode: A proposal for an ultra-wide output spectrum
We propose a novel superluminescent diode (SLD) with a quantum dot (QD) active layer, which should give a wider output spectrum than a conventional quantum well SLD. The device makes use of inhomogeneous broad...
