Nguyen holds 2 patents that showcase his groundbreaking work. His latest patents include methods and devices for solid-state nanowire devices, which offer potential advantages such as high brightness, electricity savings, long lifetime, and superior color rendering capabilities compared to traditional incandescent and fluorescent light sources. Despite these advantages, challenges remain in providing white LED lamps for general lighting applications. Nguyen and his team have established that surface recombination through non-radiative processes leads to inefficient electrical injection. They have demonstrated core-shell dot-in-a-wire LEDs that significantly improve electrical injection efficiency and output power, achieving phosphor-free InGaN/GaN nanowire white LEDs with milliwatt output power and color rendering indices of 95-98. Additionally, they have developed efficient UV nanowire LEDs for medical applications and have shown the non-degraded growth of nanowire LEDs on amorphous substrates.

Another patent focuses on high-efficiency broadband semiconductor nanowire devices and methods of fabricating them without foreign catalysis. This invention addresses the need for relatively defect-free nanowires and associated structures for group IIIA-nitrides, eliminating the requirement for foreign metal catalysts. The invention also presents self-organizing dot-within-a-dot nanowire structures, enhancing the flexibility and efficiency of these devices.
