Kagome van-der-Waals Pd3P2S8 with flat band
Seunghyun Park, Soonmin Kang, Haeri Kim +13
With the advanced investigations into low-dimensional systems, it has become essential to find materials having interesting lattices that can be exfoliated down to monolayer. One p…
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…
Studies on the high-temperature ferroelectric transition of multiferroic hexagonal manganite RMnO3
Hasung Sim, Jaehong Jeong, Haeri Kim +2
Hexagonal manganites are multiferroic materials with two highly-dissimilar phase transitions: a ferroelectric transition (from P63/mmc to P63cm) at a temperature higher than 1000 K…
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…
