Coherent control of bound entangled electrons in a CdMnTe quantum well
(WILEY-VCH Verlag, 2008-07)
Ultrafast laser pulses were used to control the spin state of a pair of entangled, donor-bound electrons in a CdMnTe quantum well. The entanglement, mediated by an optically-excited exciton, was characterized by pumpprobe ...
Epitaxial growth and characterization of GaAs/Al/GaAs heterostructures
(Elsevier, 1990-04-01)
We report on transmission electron microscopy, secondary ion mass spectroscopy, X-ray and Raman scattering studies of GaAs/Al/GaAs heterostructures grown by migration enhanced epitaxy.
Substantial pressure effect on the resistivity and Curie temperature for the diluted magnetic semiconductor Sb 2– x V x Te 3
(WILEY-VCH Verlag, 2006-07)
The influence of hydrostatic pressure on the electrical resistivity Ρ and ferromagnetic transition temperature T C of bulk, single crystal Sb 1– x V x Te 3 with x = 0.03 is presented. Pressure strongly ...
Transport and magnetic properties of the diluted magnetic semiconductors Sb 1.98– x V 0.02 Cr x Te 3 and Sb 1.984– y V 0.016 Mn y Te 3
(WILEY-VCH Verlag, 2007-06)
We report on electrical transport and magnetic properties of quaternary single crystals of Sb 1.98– x V 0.02 Cr x Te 3 and Sb 1.984– y V 0.016 Mn y Te 3 with x ranging from 0 to 0.022 and y ranging from 0 ...
An STM study of molecular-beam epitaxy growth of GaAs
(Elsevier, 1993-01-10)
Scanning tunneling microscopy has been used to investigate molecular-beam epitaxy growth of GaAs. By quenching the sample during deposition, we have imaged the GaAs(001) surface as it appeared during growth. Large scale ...
The dynamical transition to step-flow growth during molecular-beam epitaxy of GaAs(00l)
(Elsevier, 1993-12-20)
Scanning tunneling microscopy studies have been performed on GaAs homoepitaxial films grown by molecular-beam epitaxy. Images show that in the earliest stages of deposition the morphology oscillates between one with ...
Conversion of ab-initio force fields and structures to molecular mechanics energy functions
(Elsevier, 1991)
The rapid development of computers in recent years has brought increasingly complex compounds into the range of high level ab-initio calculations. Such calculations produce valuable results which in many cases would be ...
Infrared spectra of high polymers. VII. Polyacrylonitrile Presented in part at the Symposium on Molecular Structure and Spectroscopy, Columbus, Ohio, June 1957.
(Interscience Publishers, Inc.Wiley Periodiocals, Inc., 1958-09)
The infrared spectrum of polyacrylonitrile has been obtained in the extended region of 70 to 3200 cm. −1 Polarized measurements were made on stretched and rolled specimens in the range of 350 to 3200 cm. −1 . An analysis ...
A comparative study of molecular dynamics in Cartesian and in internal coordinates: Dynamical instability in the latter caused by nonlinearity of the equations of motion
(Wiley Subscription Services, Inc., A Wiley Company, 2007-04-30)
The stability of a general molecular dynamics (MD) integration scheme is examined for simulations in generalized (internal plus external) coordinates (GCs). An analytic expression is derived for the local error in energy ...
Characteristic infrared frequencies of rotational isomers of alkyl chlorides
(Elsevier, 1962)
A study of the infrared spectra of primary, secondary and tertiary alkyl chlorides reveals that the frequency of the so-called C-Cl stretching mode is a function of the detailed structure in the vicinity of the C-Cl bond. ...
