We use ballistic electron emission microscopy to investigate prototypical Au/Nb-doped SrTiO3(NSTO) Schottky barrier diodes for different temperatures and doping levels. To this end, ultrathin Au overlayers are thermally evaporated onto TiO2-terminated NSTO single crystal substrates. We show that at room temperature, regardless of the nominal...

We describe a computational approach for the automaticrecognition and classification of atomic species in scanningtunnelling microscopy images. The approach is based on apipeline of image processing methods in which the classifica-tion step is performed by means of a Fuzzy Clustering algo-rithm. As a representative example, we use the...

Ab initio nonequilibrium Keldysh formalism based on an N-order renormalization technique is used to compute I(V) ballistic electron emission microscopy characteristics at the Au/Ge(001) interface. Such a formalism quantitatively reproduces precise experimental measurements under ultrahigh vacuum and low-temperature conditions. At T=0 K, the...
