Photoinduced phase transition on black samarium monosulfide
Samarium monosulfide (SmS) is known to present a pressure-induced phase transition (BGT) from a black-colored insulator (BI) to a golden yellow colored metal (GM). To investigate the role of excitonic instability in BGT, the authors measure here the changes in electronic structure and lattice constant after pulse-laser excitations. The photoexcitation creates a photoinduced phase slightly different from the BI state, but utterly different from the GM state, suggesting that BGT requires effects other than the appearance of excitons.
