Research Interests

My re­se­arch in­te­rest is cen­te­red around novel organic semiconductors, based on organic molecules as well as hybrid perovskites. These ma­te­ri­als hold great po­ten­ti­al for the use in next ge­ne­ra­ti­on en­er­gy re­la­ted ap­p­li­ca­ti­ons such as light-emit­ting diodes and pho­to­vol­taics, as well as elec­tro­nic ap­p­li­ca­ti­ons like tran­sis­tors and me­mo­ry de­vices.

In these mul­ti­laye­red struc­tu­res, char­ge trans­port bar­ri­ers bet­ween the different se­micon­duc­tors or to the in­or­ga­nic con­tact ma­te­ri­als play a cru­ci­al role for the de­vice per­for­mance. The­re­fo­re, my re­se­arch is focus on mea­su­ring and un­der­stan­ding the en­er­ge­tic pro­per­ties of individual materials as well as their alignment at in­ter­faces using photoelectron spectroscopy. I want to cor­re­la­te fin­dings re­gar­ding the en­er­ge­tic pro­per­ties with the elec­tro­nic per­for­mance and de­vice cha­rac­te­ris­tics. Fur­ther­mo­re, I in­ves­ti­ga­te the con­cept of controlled molecular do­ping, which makes it pos­si­ble to im­pro­ve de­vice per­for­mance due to the pas­si­va­ti­on of un­wan­ted trap sta­tes and to control con­duc­tivi­ty as well as the Fermi level po­si­ti­ons.
