  • Publication number: 20130009193
    Abstract: A method of fabricating a light receiving element includes depositing a material for one of a P-type semiconductor, an N--type semiconductor, and electrodes, while applying a reverse bias voltage and irradiating light of a desired wavelength longer than an absorption wavelength of the material. The deposition has a non-adiabatic flow of, at a portion where a local shape to enable generation of near field light is formed on a surface of the deposited material with the irradiation light, absorbing the irradiation light through a non-adiabatic process with the near field light, thereby generating electrons, and canceling generation of a local electric field based on the voltage, and a particle adsorbing flow of, at a portion where the shape is not formed, causing the portion where the local electric field is generated to sequentially adsorb particles forming the material, and shifting to the non-adiabatic flow when the shape is formed.
