“…They included, for example, 2D electronic topological Lifshitz transition, 45 the emergence of superconductivity, [146][147][148] giant enhancement of thermoelectric power factor, 149,150 and also spectacular changes in the bulk mechanical, 45,151,152 electronic, [153][154][155] vibrational, and other properties. [156][157][158][159] Above 6-8 GPa, the original rhombohedral phase transforms to a monoclinic C2/m structure. 22,146,148,151,157,158,[160][161][162][163][164][165] Here, we investigated a possibility of pressure-driven p-n conductivity switching in Bi 2 Te 3 .…”
