Electronic and interface properties of polyfluorene films on GaN for hybrid optoelectronic applications
Itskos, Grigorios; Xristodoulou, X.; Iliopoulos, Eleftherios; Ladas, Spyridon; Kennou, Styliani; Neophytou, Marios; Choulis, Stelios A. (2013)Electronic and interface properties of spin-coated poly(9,9- dioctylfluorenyl-2,7-diyl) (PFO) films on GaN have been investigated in terms of their potential for optoelectronic applications. The PFO/GaN interface was studied ...
