Influence of Perfluorinated Ionomer in PEDOT:PSS on the Rectification and Degradation of Organic Photovoltaic Cells
Calvyn T. Howells, Sueda Saylan, Haeri Kim +8
Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is widely used to build optoelectronic devices. However, as a hygroscopic water-based acidic material, it brings…
Large-Scale Conformal Growth of Atomic-Thick MoS2 for Highly Efficient Photocurrent Generation
Tri Khoa Nguyen, Anh Duc Nguyen, Chinh Tam Le +6
Controlling the interconnection of neighboring seeds (nanoflakes) to full coverage of the textured substrate is the main challenge for the large-scale conformal growth of atomic-th…
Enhanced Organic Solar Cells Efficiency through Additive Electronic and Electro-optic Effects Resulting from Doping a Polymer Hole Transport Layer
C. T. Howells, K. Marbou, H. Kim +20
We demonstrate that blending fluorinated molecules in PEDOT:PSS hole transport layers (HTL) induces charge transfers which impact on both charge extraction and photogeneration with…
Influence of gas ambient on charge writing at the LaAlO3/SrTiO3 heterointerface
Haeri Kim, Seon Young Moon, Shin-Ik Kim +3
We investigated the influences charge writing on the surface work function and resistance of the LaAlO3/SrTiO3 (LAO/STO) heterointerface in several gas environments (air, O2, N2, a…
Effects of heat dissipation on unipolar resistance switching in Pt/NiO/Pt capacitors
S. H. Chang, S. C. Chae, S. B. Lee +8
We fabricated Pt/NiO/Pt capacitor structures with various bottom electrode thicknesses, , and investigated their resistance switching behaviors. The capacitors with $t_{BE}…
Epitaxial growth and the magnetic properties of orthorhombic YTiO3 thin films
S. C. Chae, Y. J. Chang, S. S. A. Seo +3
High-quality YTiO3 thin films were grown on LaAlO3 (110) substrates at low oxygen pressures (<10-8 Torr) using pulsed laser deposition. The in-plane asymmetric atomic arrangements…
