Growth mechanism of AlN by metal-organic molecular beam epitaxy
The phenomena that accompany the growth of aluminum nitride (AlN) by metal-organic molecular beam epitaxy with trimethylaluminum and ammonia as sources of aluminum and nitrogen, respectively, have been systematically investigated. Optimizing the growth temperature, flux ratios, and the ammonia injector temperature, we obtained an efficient growth with a rate of 500 nm/h and a low consumption of...
متن کاملLow-temperature formation of metal/molecular-beam epitaxy
We report soft x-ray photoemission studies of metal/molecular-beam epitaxy (MBE)GaAs(lOO) interfaces formed at low temperature. Our results indicate that rectifying barrier heights are proportional to the metal work function in accordance with Schottky's original description of metal-semiconductor contacts. These results confirm the predictions of a selfconsistent model of metal-semiconductor i...
متن کاملOperation and device applications of a valved-phosphorus cracker in solid-source molecular-beam epitaxy
Solid phosphorus is successfully incorporated into a molecular-beam epitaxy system by a valved-cracker for the growth of phosphorus-based materials. The operating parameters are established through beam flux and reflection high-energy electron diffraction measurements. InP and InGaP lattice matched to GaAs were grown and characterized by Hall measurements, photoluminescence, electroreflectance,...
متن کاملNitrides: Transition Metal Solid-State Chemistry
Together with the transition metal carbides and borides, the transition metal nitrides belong to a family of materials that features an unusual combination of outstanding properties, among which are exceptional hardness, high melting point, metallic luster with sometimes vivid colors, and simple metallic structures combined with excellent electrical and thermal conductivities. This combination ...
متن کاملHard superconducting nitrides.
Detailed study of the equation of state, elasticity, and hardness of selected superconducting transition-metal nitrides reveals interesting correlations among their physical properties. Both the bulk modulus and Vickers hardness are found to decrease with increasing zero-pressure volume in NbN, HfN, and ZrN. The computed elastic constants from first principles satisfy c11 > c12 > c44 for NbN, b...
