A. Rakitin et al., POSSIBILITY OF A DOUBLE-WELL POTENTIAL FORMATION IN DIAMOND-LIKE AMORPHOUS-CARBON, Physical review. B, Condensed matter, 58(7), 1998, pp. 3526-3528
A microscopic model, which describes specific features of the electron
ic spectrum of various allotropic forms of amorphous carbon as being r
esponsible for their structure peculiarities, is presented. It is show
n that the formation of a double-well potential is a possible driving
force for this behavior.
