Daniel E. Shai, Ph.D.
Senior Scientist
Electrical Engineering & Computer Science
  • New York

Dr. Shai has a background in solid-state physics and materials science. He has 7 years of experience involving the experimental characterization and modeling of quantum phenomena in novel materials including semiconductors, ferromagnets, superconductors, as well as materials suitable for oxide electronics, and low dimensional systems such as graphene.

Dr. Shai received his M.S. and Ph.D. in Physics at Cornell University, where his doctoral research focused on characterizing the electronic structure of complex oxide thin films and heterostructures grown by reactive oxide molecular-beam epitaxy (MBE). His work primarily centered on measuring the band structure and Fermi surface of these materials using angle-resolved photoemission spectroscopy (ARPES). He additionally has expertise in numerous other electronic characterization techniques, including electrical transport measurements, surface structure determination using low-energy electron diffraction (LEED), and core-level spectroscopies such as x-ray photoemission spectroscopy (XPS), synchrotron-based x-ray absorption spectroscopy (XAS) and x-ray fluorescence (XRF). Dr. Shai is proficient in computational techniques for solid-state physics and material science, including density functional theory (DFT) calculations and dynamical (multiple scattering) electron diffraction simulations. 

Dr. Shai has extensive experience with the design and construction of experimental apparatus, including ultra-high vacuum systems, cryogenics, instrumentation circuitry for hardware monitoring and interlocking, as well as precision motion control. He has expertise in the design of apparatus subject to complex materials constraints, including extreme temperature and high-vacuum environments.
