Abstract
We demonstrate the possibility of designing a semitransparent heater based on thin gold films. A thin 15 nm thick gold film with a surface resistivity of 3.5 Ω/□ and a transmittance in the visible range of 0.4 is deposited on a quartz substrate by pulsed laser deposition. The maximum heating temperature of the semitransparent heater is 113 °C at an applied power of 1.2 W. When a voltage is applied, the heating rate varies between 1-2 °C/s, and the rate rapidly decreases as the temperature approaches a steady state.
