Using a fermiology approach to the computation of the magnetic susceptibility measured by neutron scattering in hole-doped high-T-c superconductors, we estimate the effects on the incommensurate peaks caused by higher d-wave harmonics of the superconductin ...
We have studied by high resolution ARPES the spectroscopic properties of the prototype charge density wave system (TaSe4)(2)I and of the closely related insulating compound (NbSe4)(3)I. We observe features dispersing with the lattice periodicity, including ...
We have exploited angle-resolved photoelectron spectroscopy (ARPES) to study the electronic structure of single crystal samples of high T-c material Bi2Sr2CaCu2O8+delta and of the antiferromagnetic insulator Sr2CuO2Cl2. As one moves away from optimal dopin ...
Undoped hydrogenated amorphous silicon layers deposited at different values of very high frequency (VHF) powers and silane to hydrogen dilution ratios possess various types of microstructures. Transport and defect measurements on layers suggest that struct ...
We developed InGaAsP BRAQWET (barrier, reservoir, and quantum-well electron transfer) structures using numerical modeling to optimize the band structure. The main improvement was achieved by including i,n,i,p-doped layers in the barrier, thus decoupling th ...
A new type of material consisting of an amorphous silicon matrix, in which silicon nanoparticules are embedded, has recently been obtained. This material, named polymorphous silicon (pm-Si), exhibits enhanced transport and stability properties with respect ...
The reflectivity of TmS single crystals has been measured between 3 meV and 12 eV at room temperature and at 6 K, Besides 3p(6)-5d interband transitions a plasma edge due to free carriers is observed. In the middle infrared (near 50 meV) two sharp lines ar ...
Photoelectron spectroscopy reveals a striking correspondence between charge-density-wave-related phase transitions and modifications of the electronic structure in 1T-TaS2. High-energy-resolution spectra indicate that the collapse of the Fermi surface is a ...
A study of the formation of In- and Au-GaAs(100) interfaces is reported. The metal overlayers are deposited in ultrahigh vacuum on room-temperature (RT) and low-temperature (LT) (100)GaAs grown by molecular-beam epitaxy, following the evaporation of a prot ...
