Through a combination of experimental techniques we show that the topmost layer of the topological insulator TlBiSe _2 as prepared by cleavage is formed by irregularly shaped Tl islands at cryogenic temperatures and by mobile Tl atoms at room tempera

Publikováno v: New Journal of Physics, Vol 15, Iss 12, p 125031 (2013)

Using spin and angle-resolved photoemission spectroscopy we investigate a momentum region in Pb quantum well states on Si(111) where hybridization between Rashba-split bands alters the band structure significantly. Starting from the Rashba regime whe

Publikováno v: Crystals, Vol 9, Iss 7, p 335 (2019)

Ferroelectric materials are used in actuators or sensors because of their non-volatile macroscopic electric polarization. GeTe is the simplest known diatomic ferroelectric endowed with exceedingly complex physics related to its crystalline, amorphous
