“…The tunneling current depends on both the electronic density of states and the distance from the sample to the tip. In α-(BEDT-TTF) 2 I 3 , BEDT-TTF donors are located at the same height on the a-b surface unlike the case of θ -(BEDT-TTF) 2 RbZn(SCN) 4 [9]. Therefore, the difference in the tunneling current originates from that in the electronic density of states.…”

We performed scanning tunneling microscopy at room temperature on the conducting surface of α-(BETD-TTF) 2 I 3 , which undergoes charge ordering below T CO = 135 K. An α-type BEDT-TTF molecular arrangement was clearly observed. We observed a charge stripe structure with some inhomogeneity at room temperature. The horizontal charge stripe developed in most of the observed area. However, the coherence was restricted by the presence of charge uniform regions. The dimerization was found only between A and A . The charge disproportionation state developed on the donor arrangement, which differs from that in the charge ordered state below T CO . A certain amount of stripe structure inhomogeneity is expected to be caused by the absence of the dimer of B and C BEDT-TTF molecules. We also found a local diagonal stripe that formed the boundary between two types of horizontal stripes.

“…However, the results of the observations were macroscopic although they were site-selective measurements. There have been few position sensitive measurements of the CO states in organic conductors [9].…”
