Methods and systems of heating a substrate in a vacuum deposition process include a resistive heater having a resistive heating element. Radiative heat emitted from the resistive heating element has a wavelength in a mid-infrared band from 5 μm to 40 μm that corresponds to a phonon absorption band of the substrate. The substrate comprises a wide bandgap semiconducting material and has an uncoated surface and a deposition surface opposite the uncoated surface. The resistive heater and the substrate are positioned in a vacuum deposition chamber. The uncoated surface of the substrate is spaced apart from and faces the resistive heater. The uncoated surface of the substrate is directly heated by absorbing the radiative heat.

A heater system is provided. The system includes a resistive element with a temperature coefficient of resistance (TCR) of at least about 1,000 ppm such that the resistive element functions as a heater and as a temperature sensor and the resistive element is a material having greater than about 95% nickel. The system also includes a heater control module including a two-wire controller with a power control module that is configured to periodically compare a measured resistance value of the resistive element against a reference temperature to adjust for resistance drift over time during operation such that a temperature drift of the resistive element is less than about 1% over a temperature range of about 500° C.-1,000° C.

During a de-ice process, heating zones associated with a rotor may be supplied with power for shedding accreted ice from the heating zone. Priority heating zones associated with the leading edge of the rotor are supplied with power to activate the priority heating zones multiple times during the de-ice process. Heating zones associated with a lower surface of the rotor may be activated after the priority heating zones are first activated. A first dwell may be waited, to allow additional ice accretion on the priority zones. The priority heating zones may then be reactivated after the first dwell. Heating zones associated with an upper surface of the rotor may be then be activated. A second dwell may be waited, to allow additional ice accretion on the priority zones. The de-ice process may then repeat.
