Welcome New Physics Faculty Luis Gomez
Trent Garrison

Luis graduated as a "Licenciado en Fisica" (equivalent to a BS in Physics) from La Universidad Central de Venezuelan in 1992. He carried out his undergraduate thesis at the Instituto Venezolano de Investigaciones Cientificas (Ivic), where he synthesized the High-Temperature Superconducting compound BiSrCaCuO (BSCCO) and measured the Hall voltage on films made of this compound. Luis graduated "First-in-Class" in his promotion and was awarded a full scholarship to pursue graduate studies at the University of Cincinnati.  He obtained a Master Degree in Physics from the University of Cincinnati in 1993 after passing the Qualifying examination on five core subjects (Mechanics, Math Physics, Electrodynamics, Thermodynamics and Quantum Physics). For his Ph.D., he first studied two-dimensional arrays of Niobium crosses deposited on top of Gold films. He later got involved in the fabrication of a three-dimensional array of Niobium cubes surrounded by Titanium cubes to form what is known as a 3-D array of Josephson weak links. This project was carried out at the Cornel Nanofabrication Facility and it proved to be so challenging that to this day no one has managed to fabricate such structures. In 1997 he took a break from his studies and worked as a facilitator at the "SmartLab 2000", an initiative from the City of Cincinnati Employment and Training Division to teach the use of technology to underrepresented minorities. Luis returned to finish his Ph.D. studies in 2000 with a new project where he studied the similarities existing between a Niobium film deposited on top of a nanometer size square array of Iron dots and the Gold films with Niobium crosses that he studied earlier in his career. Thanks to his experimental experience, he managed to gather all the information he needed for his thesis after only one year of hard work.  While writing his Ph.D. thesis, he took a position as Physics instructor at Maysville Community and Technical College and also taught physics at Bracken County High School. In 2003 he wrote a thesis where he concluded that the presence of the iron dots destroyed the superconductivity state in the Niobium film that was in contact with the ferromagnetic dots, rendering a system which was, in many ways, similar to the Gold films with Niobium crosses but with a much richer dependance of its resistivity as a function of temperature. At the time of his dissertation, he could not explain satisfactorily nor further studied in more details the true origins for the destruction of superconductivity in the Niobium film, but this observation motivated him to continue investigating the physics of these systems.



Puzzled by his results and intrigued by the implications that this may have for applications, he secured a postdoctoral position at the University of Tokyo in 2005 where he developed new types of Josephson junctions devices. He proposed to deposit a strip of Iron across a micro-bridge of the High-Temperature Superconducting compound LaSrCuO (LSCO) and In 2007, he and his collaborators obtained a patent (US 8,200,304 B2) for the creation of a new type of Josephson weak link. At the end of 2007, he accepted a postdoctoral position at the Physics Institute of the University of Zurich. He collaborated in the development of single-photon detectors based on nanometer-size Niobium meander lines and later, he remained at the Physics Institute as a Visiting Scientist where he worked in new ideas for Resistive type Superconducting Fault Current Limiters based on the Hight-Temperature Superconducting compound YBaCuO (YBCO). During that time, he also though physics labs for undergraduate mayors from Zurich University. 

The exposure that he got with applied superconductivity motivated him to move to Germany in 2012 and worked as a consultant to promote the use of green energies in underdeveloped countries in South America.  In 2015, while attending several conferences in superconductivity and magnetism in Madrid, Spain, he realized an original explanation for many of his observation regarding the hybrid superconducting and magnetic bilayers systems. He remained in Spain for a year pursuing collaboration with several research groups and wrote several proposals for new research.

 His ideas were well received but after not being able to secure funds for his research, he returned to the United States in 2016 and founded Nanojunctions LLC. He wrote several research grants and contacted his former Ph.D. advisor, Prof. David Mast to collaborate in research at the University of Cincinnati. He also worked as an adjunct faculty teaching physics at UC and NKU.




In 2017, He was asked to return to NKU as a full-time faculty and he was awarded a CINSAM grant to explore the physics of Josephson weak links.

This year he is teaching PHY-110 and PHY 213 and will start his research this summer with the support of CINSAM and the UR-STEM grants.
