Laboratory name : Interface Traitements Organisation et Dynamique des Systèmes, UMR 7086

Adress : 15 rue Jean-Antoine de Baïf 75013 Paris

Contact : Philippe LANG, lang u-paris.fr

Topics :
Today, all the skills acquired on self-assembled monolayers (SAMs) and materials for electronics lead us to modify the interfaces in halide perovskite cells and transistors, using bipolar and functional SAMs. The objective is to control both the growth and the charge transfer at the interfaces or the work function.

Experimental means / theoretical tools :
The perovskite films are deposited on metal oxides ETL and HTL, modified by SAMs (stability control structure − properties)
Surface techniques : PM-IRRAS, (IR surface spectroscopy) ; UPS, XPS, MEB.
