An. Babushkin et al., THE ELECTRICAL-CONDUCTIVITY AND THERMAL ELECTROMOTIVE-FORCE OF LITHIUM HYDRIDE AND LITHIUM DEUTERIDE AT 20-50-GPA, Journal of physics. Condensed matter, 5(46), 1993, pp. 8659-8664
It has been shown that insulating LiH and LiD transform gradually to a
semiconducting state at about 30 GPa and room temperature. It was als
o found that these compounds undergo a semiconductor-to-semimetal tran
sition at about 43 GPa. The observed phenomena can probably be explain
ed by a first-order phase B1-to-B2 structure transition.
