Surface energetics and dynamics measured from STM movies
We describe a high-speed programmable-temperature scanning tunneling microscope (STM) for the study of dynamical processes and the measurement of various energies on metal surfaces. The programmable-temperature STM operates in the temperature range from 60 K to 1000 K. Over a temperature window of 300 K it can keep one particular surface area in view. We present two experimental results obtained with this instrument. The first concerns the energetics of a vicinal surface, Ag(115), and their relation with the surface roughening transition. The second treats the diffusion dynamics of kinks in steps on the (110) surface of Au.
