METHOD OF MEASURING NANOPARTICLE TEMPERATURE Russian patent published in 2011 - IPC G01Q30/02 H01J37/285 B82B3/00 

FIELD: physics.

SUBSTANCE: metal nanoparticle is placed on conducting surface from the same material at known initial temperature and on surface T₀ in conditions of thermodynamic equilibrium. Tunnel current is measured with distance between probe nanotip and nanoparticle surface by 3D scanner of tunnel microscope. Selected are conditions of nanotip touching of nanoparticle surface by jump increase in probe tunnel current that corresponds to nanocontact formation. Note here that probe is made material with electron exit conditions deferring from those of nanoparticle material. Tunnel microscope probe potential is cut off to calibrate produced nanothermocouple on heating it at known surface temperature T₁ and measure required parameters to derive nanoparticle temperature from relation (T-T₀)=V_T/α_T.

EFFECT: possibility to make measurements in nanosecond range by nanotip microstrip probe of tunnel microscope.
