In/GaAs reaction: Effect of an intervening oxide layer

Effect of Seed Layer on the Morphology of ‎Zinc Oxide Nanorods as an Electron ‎Transport Layer in Polymer Solar Cells ‎

   Zinc oxide has been considered as a promising semiconductor material for fabrication of transparent conductive oxides (TCOs), electronic devices, optoelectronics, and solar cells. Among the various morphologies of zinc oxide, nanorods are more widely used because of the ease of synthesis and providing a direct path for the transport of charge carriers. The electrochemical deposi...

Josephson effect in hybrid oxide heterostructures with an antiferromagnetic layer.

Josephson coupling between an s- and d-wave superconductor through a 50 nm thick Ca1-xSrxCuO2 antiferromagnetic layer was observed for the hybrid Nb/Au/Ca1-xSrxCuO2/YBa2Cu3O7-delta heterostructures and investigated as a function of temperature, magnetic field, and applied millimeter-wave electromagnetic radiation. The magnetic field dependence of the supercurrent I(c)(H) exhibits anomalously ra...

Capacitance-voltage studies on enhancement-mode InGaAs metal-oxide-semiconductor field-effect transistor using atomic-layer-deposited AI2O3 gate dielectric

Capacitance-voltage Characterization of Atomic-Layer-Deposited Al2O3/InGaAs and Al2O3/GaAs Metal –Oxide-Semiconductor Structures

ALD Al2O3/GaAs and Al2O3/In0.2Ga0.8As MOS and source-drain implanted MOSFET structure were fabricated and characterized by capacitance-voltage (CV) and current-voltage (I-V) measurements. It is shown that, after high-temperature anneal, the MOS leakage current density of the thinner (16nm) film is much higher than that of the thicker (30nm) film. The highquality Al2O3 (30nm)/In0.2Ga0.8As interf...

The Effect of an Intervening Promoter Nucleosome on Gene Expression

Nucleosomes, which are the basic packaging units of chromatin, are stably positioned in promoters upstream of most stress-inducible genes. These promoter nucleosomes are generally thought to repress gene expression due to exclusion; they prevent transcription factors from accessing their target sites on the DNA. However, the role of promoter nucleosomes that do not directly occlude transcriptio...
