Carrier Decay and Diffusion Dynamics in Single-Crystalline CdTe as Seen via Microphotoluminescence

Anisotropic magnetoelastic coupling in single-crystalline CeFeAsO as seen via high-resolution x-ray diffraction

Single-crystal synchrotron x-ray diffraction studies of CeFeAsO reveal strong anisotropy in the chargecorrelation lengths along or perpendicular to the in-plane antiferromagnetic (AFM) wave vector at low temperatures, indicating an anisotropic two-dimensional magnetoelastic coupling. The high-resolution setup allows to distinctly monitor each of the twin domains by virtue of a finite misfit ang...

Single-crystalline CdTe nanowire field effect transistors as nanowire-based photodetector.

The electronic and photoconductive characteristics of CdTe nanowire-based field effect transistors were studied systematically. The electrical characterization of a single CdTe nanowire FET verifies p-type behavior. The CdTe NW FETs respond to visible-near infrared (400-800 nm) incident light with a fast, reversible and stable response characterized by a high responsivity (81 A W(-1)), photocon...

Single-crystalline CdTe nanowire field effect transisitor as a nanowire- based photodetector

A schematic view of the furnace used for the CdTe nanowire synthesis by the vapor-liquid-solid (VLS) technique is shown in figure S1. In this system, the carrier gas transports the source material vapors from upstream to downstream in the quartz tube. The CdTe powder (Alfa company, 99.99%), 0.03g for all samples, was placed in a high-purity alumina crucible located at the source position of the...

Excitonic fine structure and recombination dynamics in single-crystalline ZnO

Femtosecond spectroscopy of carrier relaxation dynamics in type II CdSe/CdTe tetrapod heteronanostructures.

Branched nanocrystal heterostructures synthesized from CdSe and CdTe exhibit a type II band structure alignment that induces separation of charge upon photoexcitation and localizes carriers to different regions of the tetrahedral geometry. The dynamics of carrier relaxation examined with femtosecond pump-probe spectroscopy showed heterostructures having rise times and biexponential decays longe...
