Curriculum Vitae (CV):

Areas of Research and Professional Interest

Dr. Laraoui’ primary research focuses on developing new quantum materials based on color centers in diamond (NV, SiV, GeV), and defects in wide-bandgap semiconductors (SiC, GaN, ZnO) and two dimensional materials (hBN, TMDs) for applications in quantum sensing and quantum information processing. His current research follow four main directions:

  • Quantum sensing: nanoscale magnetic, current, and temperature mapping of condensed matter phenomena; far-field imaging of single transition metal nanoparticles (size < 20 nm).

  • Defect discovery and spectroscopy in two dimensional materials and wide bandgap semiconductors: studying the spin and optical properties of the defects, developing new quantum devices based on their performances. 

  • Quantum computing: exploring magnetic, optical, and mechanical cavities for coupling distant spin-qubits for scalable quantum networks

  • Hybrid photonics based on coupling single color centers to metamaterials for optical networks.

These research activities are mainly experimental and involve spectroscopy (optical detected magnetic resonance, fluorescence, magneto-optics), microscopy (TEM, AFM, SEM, Near-field, Confocal, Far-field, etc.), RF/MW electronics (PCB and stripline design, RF/MW equipment and pulse control), materials processing (ion beam implantation, irradiation, high temperature annealing, acid clearing, etc.), and device fabrication (E-beam, Evaporation, etching, etc.).

About Abdelghani Laraoui

Dr. Laraoui earned his PhD in Physics from University of Louis Pasteur of Strasbourg (France) where he developed a time resolved magneto-optical microscope to study the magnetization dynamics of magnetic nanomaterials excited with femtosecond laser pulses. Soon after his graduation, Dr. Laraoui received a Marie Curie fellowship from the European Research Training Network to carry a postdoctoral position at the University of Kaiserslautern (Germany). He used Brillouin Light Scattering Microscopy to study the spin current induced spin-wave emission in spin-torque nano-oscillators for applications in spintronics. After that, Dr. Laraoui joined CUNY-City College of New York as a research associate to work on a methodology to use the spin of nitrogen vacancy (NV) center in diamond as a probe for high-resolution magnetic and temperature imaging at the nanoscale. In 2016, Dr. Laraoui joined University of New Mexico’ Center for High Technology Materials as a Research Assistant Professor. He used very sensitive probes based on NV centers in diamond for imaging single iron-oxide magnetic nanoparticles  (size < 25 nm) and performing two dimensional NMR spectroscopy of microfluidics at the submicron scale. At UNM he was awarded three grants from NSF (DMR, CHE) as PI and CoPI, and from NIH (NIBIB) as a Co-Investigator .
