ABSTRACT
A detailed Raman scattering study was performed on lanthanum-modified lead titanate (PLT) with compositions varying from pure PbTiO3 to La 20.0 at. %, for temperatures ranging from 8 K to temperatures above the Curie temperature and hydrostatic pressures up to 7.5 GPa. A complete La concentration-pressure-temperature three dimensional phase diagram was determined, by using the E(TO1) soft mode frequency as the main probe.

    Using the first-principles calculations we have studied the vibrational modes and Raman spectra of a (10, 10) single-walled carbon nanotube (SWNT) bundle under hydrostatic pressure. Detailed analysis shows that the original radial breathing mode (RBM) of the SWNT bundle disappears after the...

    The effect of pressure on Raman spectra and optical absorption of β-9,10-dichloroanthracene crystals has been investigated in a diamond anvil cell up to 8 GPa hydrostatic pressure. Two pressure-induced phase transitions at about 3 and 5 GPa are observed, the latter being associated with a...
