Superconductors with broken time-reversal symmetry represent arguably one of the most promising venues for realizing highly sought-after topological superconductivity that is vital to fault-tolerant quantum computation. Here, by using extensive muon-spin relaxation and rotation measurements, we report isostructural silicide superconductors (Ta, Nb)OsSi spontaneously break at superconducting tra...

A surface roughness analysis of P-Fe%, films grown by solid phase epitaxy on Si(ll1) substrates is presented. The composition and stoichiometry of the silicides are determined by X-ray photoemission spectroscopy. Pinholes are detected in thick samples grown by the SPE method. Quantitative measurements of the roughness for different FeSi, thicknesses are based on scanning tunneling microscopy im...

An curvature measurement technique was used to characterize the stress evolution during reaction of a Ni film and a silicon substrate to form nickel silicide. Stress changes were measured at each stage of the silicide growth. When the nickel films were subjected to longtime isothermal annealing, stresses that developed during silicide formation gradually relaxed. Fitting the experimental result...
