Syed Muhammad Hafiz,Richard Ritikos,T J Whitcher,Nadia Md. Razib,Daniel Chia Sheng Bien,Narong Chanlek,Hideki Nakajima,T. Saisopa,Prayoon Songsiriritthigul,Nay Ming Huang,Saadah Abdul Rahman +10 more
TL;DR: In this paper, a carbon dioxide gas sensor from the room-temperature reduction of graphene oxide via hydrogen plasma was developed, where the hydrogen plasma contains radicals and atoms which give dissociation energies for oxygen functional groups, which is capable of reducing the graphene oxide.
Journal ArticleDOI
Determination of energy levels at the interface between O2 plasma treated ITO/P3HT?:?PCBM and PEDOT?:?PSS/P3HT?:?PCBM using angular-resolved x-ray and ultraviolet photoelectron spectroscopy
T J Whitcher,Noor Azrina Talik,Kai Lin Woon,Narong Chanlek,Hideki Nakajima,T. Saisopa,Prayoon Songsiriritthigul +6 more
TL;DR: In this article, the interfacial energy alignments at the anode of solution processable organic photovoltaics are studied using angular-resolved x-ray and ultraviolet photoelectron spectroscopy.
Journal ArticleDOI
High efficiency solution processed fluorescent yellow organic light-emitting diode through fluorinated alcohol treatment at the emissive layer/cathode interface
Calvin Yi Bin Ng,Keat Hoe Yeoh,T J Whitcher,Noor Azrina Talik,Kai Lin Woon,T. Saisopa,Hideki Nakajima,Ratchadaporn Supruangnet,Prayoon Songsiriritthigul +8 more
TL;DR: In this article, the authors compared solvent treatments using fluorinated alcohol (2,2,3,5,4,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20.2 lm W−1 (20.9 cd A−1) at a brightness of 1000 cd m−2.
Journal ArticleDOI
Enhancement of the work function of indium tin oxide by surface modification using caesium fluoride
T J Whitcher,Keat Hoe Yeoh,Yi Bin Calvin Ng,Noor Azrina Talik,Chong Lim Chua,Kai Lin Woon,Narong Chanlek,Hideki Nakajima,T. Saisopa,Prayoon Songsiriritthigul,Steffen Oswald,Boon Kar Yap +11 more
TL;DR: In this article, the work function of indium tin oxide (ITO) was modified using caesium fluoride (CsF) spincoated on top of ITO and baked while the residual CsF was washed away with DI water.
Journal ArticleDOI
The effect of carbon contamination and argon ion sputtering on the work function of chlorinated indium tin oxide
T J Whitcher,Keat Hoe Yeoh,C.L. Chua,Kai Lin Woon,Narong Chanlek,Hideki Nakajima,T. Saisopa,Prayoon Songsiriritthigul +7 more
TL;DR: In this article, the work function of indium tin oxide (ITO) was increased by treating ITO with dichlorobenzene with UV light and argon ion sputtering was used to remove the carbon contamination.
