FIG. 1.

(a) Spectral radiative heat flux for two gold or glass plates at a 100 nm gap. (b) Percentage of heat flux accumulation. The curve for blackbody radiation is calculated from Planck’s law at T = 300 K.

FIG. 2.

Reduced deflection signals by both force and near-field radiation (“green circles”), and only by force (“blue squares”) versus the gap sizes.

Image of FIG. 3.
FIG. 3.

(a) Measured near-field radiative conductance between a gold sphere and a gold substrate and comparison with the theoretical prediction from the proximity theorem. The uncertainty of gap sizes is 5 nm. (b) Equivalent sphere-plate near-field heat transfer coefficients normalized to the area 2πRd/1.46 versus gap distances. The data of SiO2-SiO2 are from Ref. 15 for the 50 µm diameter sphere. The black lines are the near-field heat transfer coefficients obtained after subtracting the far-field portion.
