We have received funds to purchase a variable-temperature, UHV, STM-AFM system with an UHV analytical chamber. The instrument has been purchased and installed and is now working. Fig. 1 shows the microscope and the UHV analytical chamber. The instrument consists of a chamber with a STM and an AFM microscope. The sample can be cooled in the range 30 K to 1000 K. Pictures can be taken at constant temperature. The sample is mounted on a manipulator that can move it in a UHV chamber where we have sources for metal vapor deposition to form clusters on the surface, thermal desorption, ion gun for sample cleaning by sputtering, Auger spectrometer to monitor surface composition and cleanliness, gas dosers to adsorb gases on the surface, and thermal desorption equipment. All these and a variety of peripherals computers, pumps, gauges, etc have been purchased with funds from the grant.
