Amorphous phases* of materials are characterized by the lack of translational or
orientational long range order. Although one might expect that the excess entropy due to …

This paper reviews the properties and phases of fullerenes and their derivatives and
compounds under high pressures. For obvious reasons most of the paper deals with C60 …

Fullerenes, containing five-and six-membered carbon rings, of which C60 and C70 are the
prominent members, exhibit phase transitions associated with orientational ordering. When …

Krätschmer and Huffman's revolutionary discovery of a new solid phase of carbon, solid
C60, in 1990 opened the way to an entire new class of materials with physical properties so …

Advances in terahertz (THz) spectroscopy and solid‐state density functional theory (DFT)
have enabled a better understanding of low‐frequency molecular phonon modes in the …

Most chemists are familiar with two kinds of inter-growths: epitaxy, which involves the
oriented over-growth of one crystalline solid upon another, and po-lytypism, which arises …

We report our high-pressure Raman studies on single-wall carbon nanotube bundles
carried out up to 25.9 GPa. The intensity of the radial modes decreases more drastically as …

In the present work in experiments in a diamond anvil cell at room temperature we studied
the behavior of glassy carbon under high pressure up to 60 GPa by means of in situ Raman …

Publisher Summary This chapter provides an introduction of fullerenes by comparing gas
phase and solid state properties, examining thin film and bulk crystal growth, and doping …

We shall discuss our recent high pressure Raman studies on single wall carbon nanotube
(SWNT) bundles and compare them with pressure‐induced amorphous and polymeric …
