Circular hole Si based on graphene/InAs for nonreciprocal thermal radiation at angle of 13° for mid-infrared region
As research into nonreciprocal thermal radiation progresses, there is a concurrent enhancement in energy conversion efficiency. However, the exploration of dual-polarized nonreciprocal thermal radiation remains insufficient. This study introduces a new method for dual-polarized nonreciprocal thermal emission using integrated graphene and magneto-optical materials. The structure is composed of reflective layer (Al), cylindrical nanopores (Si), graphene, substrate (SiO2) and InAs. Results indicate that significant nonreciprocal thermal emission can be achieved when the angle is 13° and the magnetic field intensity is 5 T for mid-infrared region. The basic physical properties of the structure are clarified, and then the influence of magnetic field intensity and incident angle on it is analyzed. Finally, the magnetic field distribution is used to further explain nonreciprocal mechanism. The bidirectional polarized nonreciprocal emission can be achieved, which has a certain value for the research of controlling and improving the nonreciprocal thermal radiation efficiency.
期刊介绍:
DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices.
The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
