To understand the electron transport properties of transition metal nitrides (MN), electronic
structure relationship between metal and corresponding nitrides is important. In binary …

The emergence and the evolution of the metallic charge transport in the La 2− x Sr x CuO 4
system from lightly to optimally doped samples (x= 0.01–0.17) are studied. We demonstrate …

In high-T c superconductors (HTS), which are layered, doped Mott insulators, weak links
occur easily in preparation and growth, being weakened further by irradiation, by impurities …

We present a study of Nernst effect in underdoped La 2− x Sr x CuO 4 in magnetic fields as
high as 28 T. At high fields, a sizable Nernst signal was found to persist in the presence of a …

We report the evolution of superconducting properties as a function of disorder in epitaxial
NbN thin films grown on (100) MgO substrates. The effective disorder in these films …

Modulation of carrier concentration in strongly correlated oxides offers the unique
opportunity to induce different phases in the same material, which dramatically change their …

We show that the doping-controlled superconductor-insulator transition (SIT) in a high
critical temperature cuprate system (Bi 2 Sr 2-x La x CaCu 2 O 8+ δ) exhibits a …

We have carried out extensive high-resolution angle-resolved photoemission (ARPES)
experiments on Bi 2 Sr 2 CaCu 2 O 8+ δ samples, covering the entire doping range from the …

We have measured the dynamics of individual magnetic fluxoids entering and leaving
photolithographically patterned thin film rings of the underdoped high-temperature …

Superconductor–insulator (SI) transitions in ultra-thin metal films, tuned either by magnetic
field or disorder, have attracted substantial attention over the last decade, because of the …
