Tunneling probe-based characterisation of the sp cubed dangling bond on the H-C(100): 2 times1 surface
Researchers used Scanning Tunneling Spectroscopy (STS) to find and characterize sp3 dangling bonds on H-terminated diamond surfaces. They observed two distinct spectral peaks at -2.1 V and +3.4 V, confirming the presence of these defects, which are crucial for quantum technologies.
