The study demonstrates the high infrared transmittance (>50% at 4-mu m-wavelength), low sheet resistance (<200 Omega square(-1) at room temperature), and high shielding effectiveness (similar to 16.2 dB at 10 GHz for the X-band) of 20-90-nm-thick Sn-doped In2O3 films deposited on an (0001)-oriented Al2O3 substrate. The multifunctional Sn-doped In2O3 films on Al2O3 substrates have potential applications in military, circuitry, windows, sensors, and transparent solar cells.
The transparency of most electromagnetic shielding conductors is limited to the visible regime. Here, we demonstrate the high infrared transmittance (>50% at 4-mu m-wavelength), low sheet resistance (<200 Omega square(-1) at room temperature), and high shielding effectiveness (similar to 16.2 dB at 10 GHz for the X-band) of 20-90-nm-thick Sn-doped In2O3 films deposited on an (0001)-oriented Al2O3 substrate. The phase persists even at 700 degrees C in air. Thus, multifunctional Sn-doped In2O3 films on Al2O3 substrates will advance technology in the areas of military applications, invisible circuitry, smart windows, infrared sensors, and transparent solar cells working in extreme environment.
