Superconductivity in a two monolayer thick indium film on Si(111) 3×3 -B

Progress of Surface and Interface Science Using Synchrotron Radiation

“…Analyzing this intensity modulation in detail with synchrotron X-rays enables the precision analysis of the surface structure [72]. The object of observation was heavy elements on the surface when CTR scattering experiments started in the 1980s; however, research has now been conducted on various low-dimensional metals on semiconductor surfaces [73,74] and light elements such as organic thin films [75] and He [76]. There have also been observations of the reduction process on the surface of battery electrodes [77].…”

Few-monolayer Ga film on Si(111): illusive gallenene formation and localization instead of superconductivity

“…For example, it has been shown that changing a bare Si(111) surface for the Si(111) ffiffiffi 3 p × ffiffiffi 3 p -B reconstruction alters the properties of the Sn submonolayer from those of a Mott insulator 9 to superconducting with T c ∼ 4.7 ± 0.3 K, [10][11][12] but does not greatly affect the superconducting properties of the two-atom-thick In film. 13 Introducing a gold interlayer promoted the superconductive properties of Pb layers on Si(100). 14 A single layer of FeSe grown SrTiO 3 exhibits a remarkably high T c above 100 K, 15 but superconductivity is absent in the FeSe layers synthesized on Bi2Se3.…”
