英文摘要	Using a microcircuit fabricated on a diamond anvil cell, we carried out in situ conductivity measurements on beta-boron at pressures up to 28 GPa. The electrical conductivity of the sample increases with increasing pressure, but it does not return to original state when the pressure returns to ambient. As the conductivity gradually increases within a temperature region from 293 to 473 K, two significant different conduction processes are observed. A possible reason for this result is proposed based on the valence band structure. In addition, by laser heating, our experimental result indicates that beta-boron still shows the transport behavior of a semiconductor.
