Latest Patents
One of his latest patents is titled "Bottom tunnel junction light-emitting field-effect transistors." This patent describes a method for achieving voltage-controlled gate-modulated light emission using monolithic integration of fin- and nanowire- n-i-n vertical FETs with bottom-tunnel junction planar InGaN LEDs. This method takes advantage of the improved performance of bottom-tunnel junction LEDs over their top-tunnel junction counterparts. It allows for strong gate control on a low-cross-sectional area fin or wire without sacrificing LED active area as in lateral integration designs. The device achieves electrical modulation of 5 orders and an order of magnitude of optical modulation.
Another notable patent is "Platforms enabled by buried tunnel junction for integrated photonic and electronic systems." This device includes a metal(III)-polar III-nitride substrate with a tunnel junction formed on one of its surfaces. It features a p-type III-nitride layer formed directly on the tunnel junction, along with several material layers. Methods for forming the device are also disclosed in this patent.
