Random defects destroy long-range phase coherence, and inhibit the metal-insulator transition in the charge density wave (CDW) system IT-TaS/sub 2/. Photoelectron spectroscopy with high resolution reveals corresponding changes in the electronic structure. ...
Redox potentials measure the free energy required to transfer a mol. species (ion) between two states of different total charge. In soln. a major contribution to the redox potential is the hydration free energy difference of the ion in the two oxidn. state ...
We carried out an ab initio investigation of the charged states of hydrogen in amorphous SiO2 using a previously generated model structure. We found a large variety of equilibrium configurations as a result of the disordered atomic structure in our model s ...
An efficient algorithm for band connectivity (BC) resoln. is presented. The method uses only readily available band coeffs. and the overlap matrix, and has a low computational cost. The accuracy of the BC resoln. is such that the method is practical for me ...
Random defects destroy long-range phase coherence, and inhibit the metal-insulator transition in the charge density wave (CDW) system 1T-TaS2. Photoelectron spectroscopy with high resolution reveals corresponding changes in the electronic structure. Core l ...
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 ...
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 ...
We report high resolution angle-scanned photoemission and Fermi surface (FS) mapping experiments on the layered transition-metal dichalcogenide 1T-TaS2 in the quasicommensurate (metallic) and the commensurate (insulating) charge-density-wave (CDW) phase. I ...
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 ...
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 ...
