We present the results of a combined study using scanning tunneling microscopy (STM) and density functional theory (DFT) of the interaction of acetone [(CH 3 ) 2 CO] with the Si(001) surface. Three distinct adsorbate features were observed using atomic-resolution STM. One of the features appears as a bright protrusion located above a Si–Si dimer, while the other two are asymmetric...
The ability to covalently attach organic molecules to semiconductor surfaces in a controllable and selective manner is currently receiving much attention due to the potential for creating novel molecular-electronic devices such as resonant tunneling diodes. Scanning tunnelling microscopy (STM) is ideally suited for such studies as it can provide information on the geometric and electronic structure...
