Hongxing Jiang

Dr. Hongxing Jiang received his BS in Physics in 1981 from Fudan University, China. He came to US through the prestigious CUSPEA program created by Nobel laureate, Prof. Tsung-Dao Lee. He obtained PhD in Physics in 1986 from Syracuse University under the guidance of the late Prof. Arnold Honig, an academic descendant of the late Nobel laureate Prof. Charles Townes. He has been working on III-nitride semiconductors since 1995. His team has invented micro-LED technology in 2000, leading to the realization of self-emissive microdisplays and microLED large panel displays. Presently, microLED is recognized as the ultimate display technology and is championed by technology giants to take on large flat panel displays and VR/3D displays. Currently, he directs the Nanophotonics Center and is the inaugural Edward E. Whitacre Jr. endowed chair and Horn Distinguished Professor of Electrical & Computer Engineering at Texas Tech University (TTU). He relocated his group to TTU in 2008 from Kansas State University where he was a University Distinguished Professor of Physics. He is the founder of 2 companies, III-N Technology, Inc. and AC-LED Lighting, LLC. His companies invented single-chip high voltage AC/DC-LEDs in 2002 and were also the first to realize video-capable self-emissive microLED microdisplay in VGA format via integration of MicroLEDs with CMOS IC in 2011, which transitioned MicroLED from prototype concept to reality and thereby stimulated worldwide efforts in MicroLED technology. High voltage DC/AC-LEDs have been commercialized worldwide, as AC-LEDs are capable to be plugged directly into standard power outlets or lamp sockets without power conversion, whereas the high voltage DC-LEDs have been widely used in automobile headlights by providing enhanced durability while reducing costs. He has been issued 19 patents. His group has recently realized boron nitride (BN) neutron detectors with a record high efficiency among solid-state detectors with the potential to displace the archaic He-3 gas detector technology. Prof. Jiang is an elected Fellow of the American Association for the Advancement of Science (AAAS) , the American Physical Society (APS), the Optical Society of America (OSA), the SPIE - the international society for optics and photonics, and the National Academy of Inventors (NAI).

Jingyu Lin

Dr. Jingyu Lin received her BS in Physics in 1983 from the State University of New York College at Oneonta. She obtained PhD in Physics in 1989 from Syracuse University under the guidance of the late Prof. Arnold Honig (an academic descendant of the late Nobel laureate Prof. Charles Townes). Dr. Lin devotes her research efforts to the development of novel materials and devices for lighting, display, energy conversion, and radiation sensing based on III-nitride wide bandgap semiconductors. She is the inaugural Linda Whitacre Endowed Chair and Horn Distinguished Professor of Electrical & Computer Engineering at Texas Tech University. In 2000, Dr. Lin co-invented the MicroLED; in 2002, she co-invented single-chip high-voltage AC/DC-LEDs for general illumination, and in 2011, she and her colleagues realized the first video-capable MicroLED microdisplay in VGA format, which transitioned MicroLEDs from prototype to reality and inspired worldwide development of MicroLED products. She is also recognized for pioneering the development in 1997 of the first “frequency-quadrupled” picosecond time-resolved optical spectroscopy system to cover the spectral range of deep UV (to 195 nm). She is the co-founder of III-N Technology, Inc. and AC-LED Lighting, LLC, which facilitated commercialization of high-voltage AC/DC LEDs and MicroLEDs. She has 19 issued patents. More recently, she and her colleagues have achieved boron nitride (BN) neutron detectors with a record high efficiency among solid-state detectors, which has the potential to revolutionize neutron detector technologies. She relocated to Texas Tech in 2008 from Kansas State University where she was a Professor of Physics. Prof. Lin is an elected Fellow of the American Association for the Advancement of Science (AAAS), the American Physical Society (APS), the Optical Society of America (OSA), the SPIE - the international society for optics and photonics, and the National Academy of Inventors (NAI).
