In this paper we report on the fabrication of all-epitaxial ultrathin germanium-on-crystalline lanthanum?yttrium-oxide field effect transistors. The oxide is lattice matched to Si (1?1?1) and has a dielectric constant of ~18. The transistors show amb

We demonstrate that depositing Ta diffusion barriers under ultra‐high vacuum conditions without in situ oxygen dosing allows for variations both in microstructure and in the concentration of chemical impurities that severely degrade barrier perform

We demonstrate the selective area growth of gallium nitride on patterned Si(111)/GaN/SiO2 wafers by metalorganic molecular beam epitaxy using triethyl gallium as a Ga source. We show that such selective area deposition may be used to grow isolated mi

This invention provides a novel hybrid organic-inorganic semiconductor light emitting diode. The device consists of an electroluminescent layer and a photoluminescent layer. The electroluminescent layer is an inorganic GaN light emitting diode struct

We examine the epitaxial incorporation behavior of the volatile p-type dopant Mg at high growth temperatures during the molecular beam epitaxy of GaN on the [0001] surface, and report interesting doping behavior. The net Mg incorporation is independe

We report a study of the desorption behavior of Ga on the GaN(0001) surface and the growth behavior of GaN during molecular beam epitaxy. A desorption activation energy of 2.2±0.2 eV is measured for Ga adatoms. Porous columnar features in the GaN mi

Interface recombination in GaAs at the GaAs/AlAs interface has been investigated before and after selective ‘‘wet oxidation’’ of the AlAs layer. Time‐resolved photoluminescence of the band‐edge GaAs emission has been used to characterize

The threshold of vertical cavity lasers has recently been greatly reduced by replacing proton implantation with selective "wet oxidation" of the AlAs layers in Bragg reflectors to provide lateral confinement of both the electrical current and the opt

Measurements of the polar Kerr rotation and optical coercivity as a function of photon energy have been made on ≊2 μm thick ThMn12‐type crystalline sputtered films of Sm(Fe,Ti)12. The optical coercivity for a Ti containing (222) textured film wa

Photocatalysis has widespread applications from solar cells to photolithography. We studied the photocatalytic properties of TiO2 films of thicknesses down to 2 nm, grown on n-type and p-type silicon wafers, using the oxidation of isopropanol as a mo
