Abstract
In SnTe–Al2O3–Al tunnel junctions with size quantization of the electron states in the SnTe electrode, oscillations of the 2nd derivative of the I(U) characteristics were observed at 4 K. From this it was possible to determine a series of points of the E(k) relation perpendicular to the film plane in a range of ±100 meV around the Fermi energy. The results are in agreement with values calculated from band structure data.Keywords
