Welcome to the Turak Research Group!

 

My research is focused on interfacial engineering in organic optoelectronic devices (OLED, OPVs). We tune the morphology, chemistry, electronic states, and structure at electrode and donor-acceptor interfaces, and study order disorder transitions in semiconducting organic thin films.

 



 

 

June 2016 – Welcome Summer Students: Fariha, Stacey, Nia, Greg, Lazar, and Haley

Jan 2016 – Welcome Joel and Riccardo, summer students from Peru!

Sept 2015 – Thanks to the summer students for a great summer!

Fall 2015 — Dr. Turak teaching Eng Phys 704 - Seminars in Photonics, Microelectronics and Nuclear.

October 2015 —Congratulations to Cristina for successfully defending her Master's Defense
