  A room temperature single-electron transistor based on the single cluster
molecule has been demonstrated for the first time. Scanning tunneling
microscope tip was used to study the transport via single carboran cluster
molecule 1,7-(CH_3)_2-1,2-C_2B_{10}H_9Tl(OCOCF_3)_2 incorporated into the
Langmuir-Blodgett monolayer of the stearic acid. DC I-V curves at 300 K showed
well pronounced Coulomb staircase, and the current could be controlled by a
lithographically fabricated gold gate electrode.
