Abstract
We report on the mutual relationship between the current-voltage (I-V) and power-voltage (P-V) characteristics in metal-vacuum-metal tunnel junctions (TJs). Performed studies of power redistribution between individual electrodes of TJ have shown good correlation of measured P-V curves with ones numerically derived from I-V characteristics. This supports our earlier proposal that careful studies of power dissipation in individual electrodes of TJ by tunneling calorimetry could be a source of similar spectroscopic information as that derived from I-V characteristics. Moreover, we advert to the possibility to extend the tunneling calorimetry for detection of energy emission processes due to charge tunneling, what represents a base for development of qualitatively new scanning probe microscopy techniques.
