Overview

Paragraph

• Luepke's material science lab focused on electronics properties of materials
• Worked on two projects
1. Phonon - Hydrogen defect coupling in perovskite crystals
2. Vortex dynamics in superconducting YBCO

Reverse isotope effect in perovskite crystals

Paragraph

• Describe environment in perovskite crystal
• Model the system using a double Morse potential to find the ground and first excited energy levels
• Using these energy level, estimate the tunneling time for the Hydrogen to travel between barriers
• Test anneal processes in new materials to explore reverse isotope effect in other materials
