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. The method takes advantage of the improved performance of bottom-tunnel junction LEDs over their top-tunnel junction counterparts, while allowing 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 significant patent is for "Light emitting diodes using ultra-thin quantum heterostructures." This patent includes a DUV-LED comprising a bottom substrate, a n-contact/injection layer formed on the bottom substrate, a p-contact region, and an emitting active region between the n-contact/injection layer and the contact region. The emitting active region includes at least one GaN quantum heterostructure, which is sized and shaped to determine a specific emission wavelength, preferably in the range of approximately 219-280 nm. The size is controlled by precisely managing parameters such as epitaxial deposition time, Ga/N ratio, thermal annealing time, and deposition temperature.
