摘要：

Charge density waves (CDW) in a tetrathiafulvalene-tetracyanoquinodimethane (TTF-TCNQ) single crystal have been studied with molecular resolution using a low temperature scanning tunneling microscope (STM). For the first time the periodicities of the CDW along both the a and b axes have been observed and were found to be coincident with those of the 2k(F) CDW. The influence of crystal singularities on the ordering of the CDW along the a axis was also revealed. [S0031-9007(98)07263-9].
