Homogeneous spectroscopic properties in manganite films
- 1. DPMC, University of Geneva, Quai Ernest-Ansermet 24, 1211 Geneva (Switzerland)
Description
The correlation between topographic features and spectroscopic properties was studied by means of room-temperature scanning tunnelling microscopy on single-crystalline fully strained La0.77Ca0.23MnO3 films. Growth terraces are atomically flat and present similar semiconducting-like tunnel current-voltage characteristics. The STM-estimated gap is in agreement with the polaron binding energy obtained from the insulating-phase resistivity. Conductance maps at different voltages do not present recognizable spatial patterns. In conclusion, 'extrinsic' phase separation is not likely in the manganite films studied
