Physics and Astronomy A. Mantilla

Alexander B. C. Mantilla

I am a Ph.D. candidate in Materials Science and Engineering working for Professor Yi Gu. My research necessitates that I work simultaneously as graduate research assistant at Washington State University and as a visiting research scientist at Pacific Northwest National Laboratory.

My work involves the ultrasensitive detection and characterization of materials with nanoscale spatial resolution via plasmon-enhanced spectroscopy. More specifically, my thesis includes:

  • Investigating the underlying physical phenomena involved with plasmon-enhanced, scanning probe-coupled, tip-enhanced spectroscopy.
  • Implementing tip- and plasmon-enhanced spectroscopy for the nanoscale characterization and tuning of 2D semiconductor and ferroelectric devices.

I received my B.Sc. in Physics from Central Washington University in 2020. In undergrad, my research was split between two published projects:

  • Growth and structural/thermal/magnetic characterization of perovskites at ultralow temperature.
  • Computational modeling of simulated particle diffusion.
