TcS 2在28 GPa以上经历电荷转移绝缘体到金属的转变。激光退火揭示了一个动力学受阻的高压毒砂相，可恢复到环境。新相类似于Mn-二硫属化物而不是预期的Re-二硫属化物，并且涉及S-S和Tc-Tc键的形成。
TcS2 undergoes a charge transfer insulator to metal transition above 28 GPa. Laser annealing reveals a kinetically hindered high pressure arsenopyrite phase that is recoverable to ambient. The new phase is similar to the Mn-dichalcogenides rather than the expected Re-dichalcogenides and involves the formation of S–S and Tc–Tc bonds.
