Efficiency improvement in the cantilever photothermal excitation method using a photothermal conversion layer [PDF]

Beilstein Journal of Nanotechnology, 2016
Photothermal excitation is a cantilever excitation method that enables stable and accurate operation for dynamic-mode AFM measurements. However, the low excitation efficiency of the method has often limited its application in practical studies. In this study, we propose a method for improving the photothermal excitation efficiency by coating cantilever

AMORPHOUS SILICON IN PHOTOTHERMAL CONVERSION

Le Journal de Physique Colloques, 1981
Efficient conversion of solar energy into heat requires a spectrally selective surface to function as a one-way valve between the incident radiation and heat transfer system. The tandem action of a solar absorber overlying an infrared reflector gives this action, provided the absorber is transparent in the thermal infrared /l/. Our group has fabricated
