Small Cavity Nonresonant Tunable Microwave-Frequency Alternating Current Scanning Tunneling Microscope

reportActive / Technical Report | Accession Number: ADA285752 | Open PDF

Abstract:

We have developed a broadly tunable microwave frequency alternating current scanning tunneling microscope which employs a cavity with no resonances in the frequency range used. This results in a low flat background for spectroscopic measurements with this instrument.
