Homebuilt Low Temperature Microscope
SPM 1000 Control System
Manipulated single azobenzene molecule using several different techniques with a low temperature scanning tunneling microscope (STM).
Operating at a temperature of 34K the isolated azobenzene molecules on the Au(111) surface are selectively and reversibly switched by a 1 microsecond long, -3 V pulse. The imaging parameters are -1.25V, 50 pA.
