Instrument
Single molecular vibration spectroscopy

Single molecular junction is fabricated by mechanically controllable break junction (MCBJ) technique at 4 K in ultra high vacuum. Molecule is introduced to metal nano gap through the heated capillary.
Shot noise

Single molecular junction is fabricated by MCBJ at 4 K in UHV. The noise signal from the molecular contact is amplified by two parallel sets of low-noise preamplifiers. The cross spectrum is taken using the two-channel spectrum analyzer.
Photochemical reaction of single molecule

Single molecular junction is fabricated by MCBJ at 4 K in UHV. The photo is irradiated through glass fiber.
