    Abstract: A solid-state light source with built-in access resistance modulation is described. The light source can include an active region configured to emit electromagnetic radiation during operation of the light source. The active region can be formed at a p-n junction of a p-type side with a p-type contact and a n-type side with a n-type contact. The light source includes a control electrode configured to modulate an access resistance of an access region located on the p-type side and/or an access resistance of an access region located on the n-type side of the active region. The solid-state light source can be implemented in a circuit, which includes a voltage source that supplies a modulation voltage to the control electrode to modulate the access resistance(s).

    Abstract: A normally-off transistor with a high operating voltage is provided. The transistor can include a barrier above the channel and an additional barrier layer located below the channel. A source electrode and a drain electrode are connected to the channel and a gate electrode is connected to the additional barrier layer located below the channel. The bandgap for each of the barrier layers can be larger than the bandgap for the channel. A polarization charge induced at the interface between the additional barrier layer below the channel and the channel depletes the channel. A voltage can be applied to the bottom barrier to induce free carriers into the channel and turn the channel on.
