A low temperature ultra-high vacuum scanning tunneling/force microscope (LT UHV STM/SFM) has been designed and constructed for imaging, spectroscopy, and manipulation at the atomic scale. This microscope is capable of operating in either STM or SFM modes through in-situ tip exchange. In addition, simultaneous STM/SFM is also possible using a conductive SFM tip. Our goal is to investigate inter- and intra-molecular forces between small molecules on metal surfaces, to explore the relation between electronic and mechanical properties, and to perform electronic, vibrational, and force spectroscopy. Preliminary STM images and scanning tunneling spectra of single-molecules will be presented.
