| Abstract: | Electrical nano-scale crystallization and amorphization in amorphous and crystalline Ge2Sb2Te5 films have been studied using scanning probe microscopes. In scanning tunneling microscopes, the phase changes can be induced, not by tunneling currents, but by conducting currents flowing through contacted probes. In an atomic force microscope, metallic cantilevers can produce phase-change marks with minimal sizes of 10 nm. The crystallization and amorphization processes show different dependences upon thickness of Ge2Sb2Te5 films. These features are discussed from thermo-dynamical and microscopic structural points-of-view. |
