Abstract:
1. A method for characterizing electronic trap states at multiple locations in a dielectric material, comprising: providing an oscillating probe tip operable for electron tunneling; making respective surface potential measurements associated with respective electron tunneling attempts from each of multiple distances including at least different first and second distances between the probe tip and the dielectric material at a first location, and wherein some of the respective surface potential measurements associated with respective electron tunneling attempts at each of the first and second distances are associated with respective electron tunneling attempts at each of multiple applied voltages including at least different first and second voltages; making respective surface potential measurements associated with respective electron tunneling attempts from each of multiple distances including at least different third and fourth distances between the probe tip and the dielectric material at a second location that is different from the first location, and wherein some of the respective surface potential measurements associated with respective electron tunneling attempts at each of the third and fourth distances are associated with respective electron tunneling attempts at each of multiple applied voltages including at least different third and fourth voltages; and using the respective surface potential measurements to characterize energy and/or depth of the electronic trap states at the first and second locations in the dielectric material.
