- Biography
I am interested in computational nuclear materials research, particularly in the context of space research, electronics, and radiation-matter interactions. In addition, I look to help improve the sustainable, efficient, and decentralized energy options nuclear provides. I am a current Ph.D. student at PSU after graduating Summa Cum Laude from RPI with a dual degree in nuclear and materials engineering. I also interned at LANL in the NEN-2 group performing modeling in support of nuclear criticality safety and nuclear data research.

Gallium nitride, aluminum nitride, and their ternary alloys form an important class of wide-bandgap semiconductors employed in a variety of applications, including radiation-hard electronics. To better understand the effects of irradiation in these materials, molecular dynamics simulations were employed to determine the threshold recoil energies to permanently displace atoms from crystalline sites. Threshold displacement energies were calculated with the lattices at 0 K. Thermal effects are found to lower the threshold energies by ∼1 eV. The threshold energy knockout events observed result in Frenkel pair defects. The electronic structure and dynamics of these Frenkel pair defects are analyzed and the consequences for device operation are discussed. |
