TL;DR: In this paper, a 50-keV Ga+ focused ion beam (FIB) in the fluence range of 1x1014 -2x10^16 ions cm^-2 is used for the irradiation process.
Journal ArticleDOI
Electronic structure of GaN nanowire studied by x-ray-absorption spectroscopy and scanning photoelectron microscopy
J. W. Chiou,J. C. Jan,H. M. Tsai,W. F. Pong,Mong-Hsun Tsai,I.-H. Hong,R. Klauser,J. F. Lee,C. W. Hsu,H. M. Lin,Chia Chun Chen,C. H. Shen,Li-Chyong Chen,Kuei-Hsien Chen +13 more
TL;DR: In this article, X-ray absorption near edge structure (XANES) and scanning photoelectron microscopy (SPEM) measurements have been employed to obtain information on the electronic structures of the GaN nanowires and thin film.
Journal ArticleDOI
Thermionic emission of amorphous diamond and field emission of carbon nanotubes
TL;DR: In this paper, the authors reported that amorphous diamond emitted more than 13 times more electrons at a temperature of 300 ˚C than at room temperature, while carbon nanotubes exhibited no increase of emitted current upon heating to 300 ǫC.
Journal ArticleDOI
Passivation of GaSb using molecular beam epitaxy Y2O3 to achieve low interfacial trap density and high-performance self-aligned inversion-channel p-metal-oxide-semiconductor field-effect-transistors
R. L. Chu,Tsung-Hung Chiang,W. J. Hsueh,Kuei-Hsien Chen,Keng-Hua Lin,Gail J. Brown,J.-I. Chyi,J. Kwo,Minghwei Hong +8 more
TL;DR: In this paper, high-κ/GaSb interfacial properties were better in samples with a high substrate temperature of 200°C than in those with high κ's deposited at room temperature, in terms of the interfacial electrical properties, particularly, the reduction of interfacial trap densities near the conduction band and the MOSFET device performance.
Journal ArticleDOI
High performance of catalysts supported by directly grown PTFE-free micro-porous CNT layer in a proton exchange membrane fuel cell
He-Yun Du,Chen-Hao Wang,Hsin-Cheng Hsu,Sun-Tang Chang,Shi-Chern Yen,Li-Chyong Chen,Balasubramanian Viswanathan,Kuei-Hsien Chen,Kuei-Hsien Chen +8 more
TL;DR: In this paper, the performance of a proton exchange membrane fuel cell (PEMFC) with a catalytic layer consisting of low loading of platinum nanoparticles (0.05 mg cm−2) supported by a directly grown micro-porous carbon nanotube (CNT) layer without incorporation of polytetrafluoroethylene (PTFE) was evaluated.
