Sažetak
The metal-insulator transition in BaVS3 was studied at ambient pressure and under hydrostatic pressure up to p=26 kbar in the energy range of 2.5-500 meV. The charge gap determined from the optical reflectivity was enhanced, Deltach(p)/kBTMI (p)12. This ratio is independent of pressure, indicating that the character of the transition did not vary along the p-T phase boundary. Above the critical pressure, pcr~20 kbar, metallic spectra were recorded in the whole temperature range, as expected from the shape of the phase diagram.
