摘要：

The anchoring structures of smectic liquid crystals, n-alkylcyanobiphenyl (mCB: m = 8, 10, 12), on molybdenum disulfide (MoS2) are directly observed by scanning tunneling microscopy (STM) in order to analyze the alignment mechanism of liquid crystals. For 8CB, the anchoring structure is of the periodic monolayer type, while 10CB and 12CB take a bilayer structure in which there is no interdigitation of the cyano groups. These structures on MoS2 depend on the length of the alkyl group in contrast to those on graphite. The mechanism of alignment is discussed based on the STM results.
