- Sequential Regeneration of Self-Assembled Monolayers for Highly Selective Atomic Layer Deposition
Fatemeh Sadat Minaye Hashemi and Stacey F. Bent
Version of Record online: 27 SEP 2016 | DOI: 10.1002/admi.201600464
Sequential regeneration of self-assembled monolayers (SAMs) improves their blocking properties against atomic layer deposition, allowing for selective deposition of dielectric films on patterned substrates more than three times thicker than approaches that do not regenerate the SAM. This vapor process reduces artifacts associated with selective deposition of thin films on 3D structures and decreases the required deposition time for the passivation layer.
- Engineering TiO2/Perovskite Planar Heterojunction for Hysteresis-Less Solar Cells
Vanira Trifiletti, Norberto Manfredi, Andrea Listorti, Davide Altamura, Cinzia Giannini, Silvia Colella, Giuseppe Gigli and Aurora Rizzo

Perovskite material quality has a preeminent impact on hysteresis. The presented method relies on solvent engineering during the casting process, leading to a thick film that ensures an optimal interface connection with the charge-extracting layer. This method allows obtaining perovskite active layer with superior optical properties, explaining the ideal device behavior and device performances.
- Giant Vesicles Exposed to Aqueous Two-Phase Systems: Membrane Wetting, Budding Processes, and Spontaneous Tubulation
Rumiana Dimova and Reinhard Lipowsky
Version of Record online: 26 SEP 2016 | DOI: 10.1002/admi.201600451
Recent studies of giant vesicles encapsulating aqueous two-phase polymer solutions are reviewed. These systems exhibit a variety of rather interesting processes: aqueous phase separation leading to complete or partial membrane wetting, droplet-induced budding of vesicles, and spontaneous tubulation of membranes arising from the asymmetric adsorption of polymers. New methods to determine the spontaneous curvature of the membranes in a quantitative manner are also described.
- Growth and Differentiation of Myoblastic Precursor Cells on Thin Films of Metallo-Supramolecular Coordination Polyelectrolyte (MEPE)
Janina Belka, Tobias Weigel, Ann-Kathrin Berninger, Dirk G. Kurth and Joachim Nickel
Version of Record online: 26 SEP 2016 | DOI: 10.1002/admi.201600272
Pre-myoblast C2C12 cells adhere and proliferate on Fe(II)-based metallo-supramolecular polyelectrolyte (MEPE) substrates. Differences in cell morphology and elevated metabolic activities are detected. The substrates positively affect myogenic differentiation, which might be stimulated by iron(II) released from the MEPE layer.
- A New Look at the Electronic Structure of Transparent Conductive Oxides—A Case Study of the Interface between Zinc Magnesium Oxide and Cadmium Telluride
Douglas A. Duncan, Rueben Mendelsberg, Michelle Mezher, Kimberly Horsley, Samantha G. Rosenberg, Monika Blum, Gang Xiong, Lothar Weinhardt, Markus Gloeckler and Clemens Heske
Version of Record online: 20 SEP 2016 | DOI: 10.1002/admi.201600418
A novel approach to characterize the electronic structure of transparent conductive oxides, namely, to distinguish between optically and transport-relevant states is presented. Consequently, “optical” and “electronic” band offsets at the CdTe/(Zn,Mg)O interface are derived and it is demonstrated that the “electronic” band offset is suitable for electron transport across the interface (a flat conduction band alignment of 0.02 ± 0.20 eV), while the “optical band offset” is not (a significant 0.48 ± 0.20 eV spike).
