Congratulations to Shan-Wen and Jack for being awarded the Departmental Miller Teaching Awards!
Ding's opus on a new, powerful imaging approach to track coherent polariton propagation and interactions in cavities and 2D materials was just posted on arXiv!
Vicky's paper on dark exciton funneling appears in Nano Letters!
Check out Vicky's paper on dark exciton funneling in dielectric nanobubbles, the first time this phenomenon has been observed thanks to scattering microscopy and some great work from Vicky! Just posted on arXiv.
Very exciting times for the lab - we moved the last setup from our temporary space into our brand new labs, completing our move. A new phase begins...
Paul Brown joins the lab as a graduate student. Paul is a graduate from Northwestern University where he did some beautiful work on quantum dot / 2D material interfaces. Welcome to the group Paul!
Rahawa Ghebrelul joins the lab as an undergraduate research from Biomedical Engineering - welcome Rahawa!
After 1.5 years of research on exciton transport in 2D materials in the Delor labs, Eileen starts as a Bridge scholar - congratulations Eileen, we will miss you!
Athena returns to Yale to continue her undergraduate after a successful REU project designing compression cells and studying energy flow in materials under pressure. It was wonderful to have you join us for the summer Athena!
The group welcomes MRSEC REU student Athena Stenor, who is joining us from Yale Chemical Engineering - welcome Athena!
The group welcomes new postdoc James Baxter from Imperial College. James did his PhD in ultrafast protein crystallography using lots of super-cool optical and X-ray techniques - welcome to the group James!
Ding, Vicky and Shan-Wen pass their second year defenses, congratulations all around!
Ding receives the well-deserved 2020-2021 Kasindorf Fellowship from Columbia for his outstanding 1st year achievements - congratulations Ding!
Exciting additions to the group! Will Carson from Miami University joins as a Columbia MRSEC REU student; Jack Tulyag and Inki Lee, incoming Columbia graduate students, join as summer GRAs.
New article out in ACS Energy Letters! Using stroboSCAT to image charge transport in two lead-free double halide perovskites, we find that carrier diffusion lengths exceed 1 micron despite shallow trap-limited transport. These diffusion lengths combined with good absorption properties suggest that halide double perovskites are viable candidates to rival the archetypal lead halide perovskites for photovoltaic applications.
Eileen Moudou, an undergraduate student at Columbia College, joins the group. Welcome!
Milan is awarded the Lenfest Junior Faculty Development Grant. Thank you to the Lenfest program!
Graduate students Shan-Wen Cheng, Vicky Su and Ding Xu join Delor Labs. Welcome!
The Delor lab is growing! We are looking for enthusiastic students and postdocs to join the team in Fall of 2019. Please contact Milan for more information.
