It allows the visual contact of outdoor environment for people inside the building, and lets natural light enters into the room. In regard to energy saving, windows are weak links in the building energy system because of their high thermal losses and high solar heat gain, leading to the heating or cooling needs for a building. In this proposal, we emphasize on the control of infrared (heat) transmittance of glass panels. The fundamental of this proposal is to use sputtered MgO/MgZnO/ZnO multiple-quantum well as infrared absorber (MQW IR absorber, in brief) to electrically control the wavelength-passing range of infrared through window glass panels by applying an electrical fields. When the electromagnetic (EM) waves pass through the MQW IR absorber coated windows, the EM waves with wavelengths corresponding to the intersubband transition energy level differences are being absorbed when Fermi golden rule is fulfilled. The absorbed wavelengths of infrared can be designed through the thickness control of barrier and well layers of MQW, which is commonly called bandgap engineering. Once the absorption wavelength range is determined, the absorption can still be fine-tuned by applying an external field, which modulates slightly the sub-band levels and the intersubband transition probability. A Monte Carlo photon simulation will also be performed to study the transmission of this superlattice structure.節能窗智慧窗紅外線超晶格多重量子井蒙地卡羅光子模擬過渡金屬氧化物Energy-efficient windowintelligent windowsmart windowinfraredsuperlatticemultiple quantum wellMonte Carlo photon simulationtransition metal oxide
