STMによるHOPG基板上のシアノビフェニル系液晶7CB, 9CBの観察

抄録

We observed the arrangement of cyanobiphenyl liquid crystals (mCB: m=6 to 12) on highly oriented pyrolytic graphite (HOPG) substrates, and 6CB on molybdenum disulfide (MoS₂) by scanning tunneling microscopy (STM). The already reported arrangements were reaffirmed in 8CB, 10CB, 11CB and 12CB. In case of 6CB, the arrangement which had both single-and double-row properties were observed. In case of 7CB and 9CB, the single-row structures were observed for the first time.The characteristic point was that the arrangements were divided into single- and double-row structures accordint to the odd-even effct.
