Summer Research Goals NSF REU INM Introductory Day for RET Participants - July 6, 2015
§ Optimize deposition process § Uniform coating
Fig. 8 0.05 g Diatom coated with TiO2
Fig. 9 0.15 g Diatom coated with TiO2
§ Incorporate monolayers into solar cells
§ Positives: § Hands on clean room experience § Opportunity to take a project from start to finish § Dedicated faculty and graduate school mentors § Provides both freedom and structure
§ Week 1: § Step-by-step introduction to the process § Goal – peace of mind and familiarity with progress
