Journal ArticleDOI
The influence of hydrogenation and oxygen vacancies on molybdenum oxides work function and gap states for application in organic optoelectronics.
Maria Vasilopoulou,Antonios M. Douvas,Dimitra G. Georgiadou,Leonidas C. Palilis,Stella Kennou,Labrini Sygellou,Anastasia Soultati,Ioannis Kostis,Giorgos Papadimitropoulos,Dimitris Davazoglou,Panagiotis Argitis +10 more
TL;DR: This work aims to investigate the beneficial role of hydrogenation (the incorporation of hydrogen within the oxide lattice) versus oxygen vacancy formation in tuning the electronic structure of molybdenum oxides while maintaining their high work function.
Journal ArticleDOI
Structure-dependent electronic properties of nanocrystalline cerium oxide films
TL;DR: In this paper, the authors investigated the electronic properties of nanocrystalline cerium oxide (CeO) films and established universal relations between them and the film structure, composition, and morphology.
Journal ArticleDOI
Thermal degradation mechanisms of PEDOT:PSS
Evangelos Vitoratos,S. Sakkopoulos,E. Dalas,N. Paliatsas,Dimitrios Karageorgopoulos,Foteini Petraki,Stella Kennou,Stelios A. Choulis +7 more
TL;DR: In this article, the thermal stability of thin PEDOT:PSS films was investigated by dc conductivity measurements, X-ray and UV photoelectron spectroscopies as a function of heating temperature and heating time.
Journal ArticleDOI
Origin of non-faradaic electrochemical modification of catalytic activity
TL;DR: In this article, the effect of electrochemical oxygen pumping on Pt catalyst films interfaced with an O 2 -conducting yttria-stabilized zirconia solid electrolyte was investigated.
Journal ArticleDOI
Old metal oxide clusters in new applications: spontaneous reduction of Keggin and Dawson polyoxometalate layers by a metallic electrode for improving efficiency in organic optoelectronics.
TL;DR: A large improvement in the operational characteristics of organic light emitting devices and organic photovoltaics based on a wide range of different organic semiconducting materials and incorporating reduced Pom/Al cathode interfaces was achieved as a result of the large decrease of the electron injection/extraction barrier, the enhanced electron transport and the reduced recombination losses in the reduced POM modified devices.
