Absorptivity control of objects using micro- and Thermal radiation is a ubiquitous form of electromagnetic radiation thatĮmanates from objects with finite temperature, and its spectrum can beīy the absorptivity of the object (Kirchhoff’s law ). © 2021 Optical Society of America under the terms of the OSA Open Access To lead to new energy harvesting technologies. The theory developed here will be a firm foundationįor exciton thermal radiation in 1D semiconductors, which is expected The calculations show that theĮxciton state, which is an electron–hole pair mutually bound by theĬoulomb interaction, causes enhancement of the radiation spectrum peakĪnd significant narrowing of its linewidth in the near-infrared Spectrum of semiconducting single-walled carbon nanotubes as a We derive a simple and useful formula for theĮmissivity, which is then used to calculate the thermal radiation Investigate thermal radiation from one-dimensional (1D) semiconductorsĬharacterized by the strong quantum correlation effect due to theĬoulomb interaction. Low-dimensional materials is promising because of its inherent ability Among the various proposed methods, quantum confinement in Highly efficient and functional utilization of thermal radiationĮnergy. Spectral control of thermal radiation is an essential strategy for Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored.Use a comma to separate multiple people: J Smith, RL Jones, Macarthur.Use these formats for best results: Smith or J Smith.For best results, use the separate Authors field to search for author names.Use quotation marks ' ' around specific phrases where you want the entire phrase only.Question mark (?) - Example: 'gr?y' retrieves documents containing 'grey' or 'gray'.Asterisk ( * ) - Example: 'elect*' retrieves documents containing 'electron,' 'electronic,' and 'electricity'.Improve efficiency in your search by using wildcards.Example: (photons AND downconversion) - pump.Example: (diode OR solid-state) AND laser.Note the Boolean sign must be in upper-case. Separate search groups with parentheses and Booleans.Keep it simple - don't use too many different parameters.
