Boosting interfacial charge transfer for efficient water-splitting photoelectrodes: progress in bismuth vanadate photoanodes using various strategies
TL;DR: In this paper, the authors highlight the important strategies that have been made for improving the performance of the photoanode material, such as fabricating nanostructured electrode, controlling reacting facet, stacking with other materials, utilizing plasmonics, loading co-catalyst, and controlling the interfacial band bending with ferroelectrics.
Journal ArticleDOI
Stabilization of NiFe Layered Double Hydroxides on n-Si by an Activated TiO2 Interlayer for Efficient Solar Water Oxidation
Sungkyun Choi,Sol A Lee,Hyunwoo Yang,Tae Hyung Lee,Changyeon Kim,Chung Won Lee,Hyunjung Shin,Ho Won Jang +7 more
TL;DR: NiFe layered double hydroxides (LDH) on n-Si can be an expectable photoanode because of its advantages of earth-abundant materials, high photoelectrochemical properties, and wide solar spectrum as mentioned in this paper.
Journal ArticleDOI

Abbas Sabahi Namini,Seyed Ali Delbari,Yeonju Oh,Mehdi Shahedi Asl,Quyet Van Le,Joo Hwan Cha,Sea-Hoon Lee,Ho Won Jang,Heung Nam Han,Mohammadreza Shokouhimehr +9 more
TL;DR: In this paper, the effect of TiCN on the microstructure development of spark plasma sintered fully dense ZrB2-based ceramics was investigated, and the Vickers hardness and elastic modulus of the (Zr,Ti)B2 matrix in the ternary system were measured to be 29.3 and 450.8 GPa, respectively.
Journal ArticleDOI
Microstructural study of Pt contact on p-type GaN
Jong Kyu Kim,Ho Won Jang,Chong Cook Kim,Jung Ho Je,Kimberly Anne Rickert,Thomas F. Kuech,Jong-Lam Lee +6 more
TL;DR: In this paper, the biaxial tensile strain at the interface of the Pt layer (100 A) with p-type GaN was investigated as a function of annealing temperature.
