Results of angle dispersive X-ray diffraction (ADXRD) measurements on the defect chalcopyrites (DCP), HgAl 2 Se 4 and CdAl 2 S 4 up to 22.2 and 34 GPa, respectively, are reported. The ambient tetragonal phase is retained in HgAl 2 Se 4 and CdAl 2 S 4

Results of a high-pressure angle dispersive X-ray diffraction and electrical resistance study on quasi one-dimensional BaVS3 are reported. They show that no structural transition occurs up to 26 GPa. However, there is evidence of gradual disordering

The results of electrical resistance and angle dispersive X-ray diffraction measurements at high pressures and ambient temperature on the chalcogenide spinel, CuIr 2 S 4 are reported. The resistance increases gradually and reaches around 12 GPa a val

This work presents a time-resolved spectroscopic study of MnF2 as grown and milled into nanoparticles. We find that high pressure (HP) induces photoluminescence (PL) at room temperature (RT) above 13 GPa in MnF2 single crystals. RT-PL occurs as a con

We report the results of an X-ray diffraction study of CdAl 2 Se 4 and of Raman studies of HgAl 2 Se 4 and ZnAl 2 Se 4 at room temperature, and of CdAl 2 S 4 and CdAl 2 Se 4 at 80 K at high pressure. The ambient pressure phase of CdAl 2 Se 4 is stabl

We report the results of electrical resistance measurements at high pressures on Cs 2 MoS 4 and KTbP 2 Se 6 . The results of high pressure X-ray diffraction study of Cs 2 MoS 4 are also presented. Interestingly, in the case of Cs 2 MoS 4 the resistan

The role of high pressure experiments in the discovery of supercon ducting materials with a T. above liquid nitrogen temperature has demon strated the importance of such experiments. The same role holds true in the tailoring of materials for opto

We have observed a pressure induced phase transition in KTbP 2 Se 6 at about 9.2 GPa which was accompanied by a discontinuous jump of the absorption edge of about 0.5 eV into the red. We have proposed that the high pressure phase is due to charge tra
