Autor: Sukang Bae, Hyojung Bae, Hyunjung Lee, Dae-Hwa Mun, Jun-Seok Ha, Sang Hyun Lee

Publikováno v: physica status solidi (RRL) - Rapid Research Letters. 8:341-344

GaN microstructures were grown on c-Al2O3 with a multi-stacked graphene buffered layer using metal metal-organic chemical-vapor deposition. Under the same growth conditions, the nucleation of GaN was suppressed by the low surface energy of graphene,

Acidic PEDOT:PSS anode buffer layers (ABLs) are widely used for improving efficiency in organic based solar cells. Recently, stable p-type metal oxides, such as NiO, MoO3, and V2O5, have been used to replace the commonly used acidic PEDOT:PSS ABL. Am

Effects of Controlling the AZO Thin Film's Optical Band Gap on AZO/MEH-PPV Devices with Buffer Layer

Autor: Hyojung Bae, Dae-Hwa Mun, Hang-Ju Ko, Jaehyoung Park, Young-Bu Mun, Ki-Chang Jung, Jun-Seok Ha, E. M. Han, Ari Lee

Publikováno v: International Journal of Photoenergy, Vol 2012 (2012)

Organic/inorganic hybrid solar cells were fabricated incorporating aluminum-doped zinc oxide (AZO) thin films of varying optical band gap in AZO/poly(2-methoxy-5-(2′-ethyl-hexyloxy)-p-phenylene vinylene) structures. The band gaps were controlled by

Photocatalytic decomposition of graphene over a ZnO surface under UV irradiation

Autor: Sang Hyun Lee, Dae-Hwa Mun, Sukang Bae, Hyunjung Lee, Tea-Wook Kim

Publikováno v: Physical chemistry chemical physics : PCCP. 17(24)

Highly reactive radicals or chemicals are generated on the surfaces of oxide semiconductors via reactions between photo-induced charges and ambient gas molecules. These radicals or chemicals have been utilized in heterogeneous photosynthesis and phot
