Bias voltage refers to a small and constant electric voltage that is applied to electronic components or devices. It helps to keep them in a stable and preferred operating condition, making sure they function properly and accurately. Full definition
Increasing the energy levels would impact the on / off ratio of the device, perhaps also decreasing the power needed for switching on the device if more energy levels become accessible for transiting electrons at low bias voltages. (sciencedaily.com)
By modeling the absorber using a transmission line, the researchers found that the varactor provides a variable capacitance at varying bias voltage, which produces the device's tunability, while the lumped resistor with constant resistance reliably produces strong absorption at the resonance frequency.

Emission currents of 0.1 to 1 microampere were readily obtained at room temperature with bias voltages of less than 80 volts. (science.sciencemag.org)
