“…63 Using electrospinning, extremely long (up to 1 cm) but very thin (40 nm diameter) GaN nanofibers could be produced, using poly(vinyl pyrrolidone) (PVP) as the matrix polymer. 64 When exposed to UV light, the conductance of these semiconductors greatly increased, resulting in an electric signal as output for UV detection. The conductance of the electrospun GaN nanowires increased nearly 830 times which is over 10-fold higher than for GaN nanowires produced by classical chemical vapour deposition.…”

“…Extremely long GaN nano bers on a large scale can be synthesized based on electrospinning. The strategy to obtain GaN nano bers can be divided into three steps: (1) The electrospinning of precursor composite nano bers that comprise polymer and gallium nitrate; (2) Calcination of the composite nano bers in air to thoroughly remove organic components and to form gallium oxide nano bers; (3) In situ conversion of the as-prepared oxide nano bers into nitride nano bers in an ammonia atmosphere at high temperature [50]. SEM image shows that the continuous structure of the initial Ga 2 O 3 nano ber was maintained after ammonization.…”

This paper provides a brief review of current research activities that focus on the synthesis and controlled assembly of inorganic nano bers by electrospinning, their electrical, optical and magnetic properties, as well as their applications in various areas including sensors, catalysts, batteries, filters and separators. We begin with a brief introduction to electrospinning technology and a brief method to produce ceramic nanofibers from electrospinning. We then discuss approaches to the controlled assembly and patterning of electrospun ceramic nanofibers. We continue with a highlight of some recent applications enabled by electrospun ceramic nano bers, with a focus on the physical properties of functional ceramic nanofibers as well as their applications in energy and environmental technologies. In the end, we conclude this review with some perspectives on the future directions and implications for this new class of functional nanomaterials. It is expected that this review paper can help the readers quickly become acquainted with the basic principles and particularly the experimental procedure for preparing and assembly of 1D ceramic nanofiber and its arrays.

“…[6][7][8] For this reason, photodetectors commonly use materials such as ZnO, SnO 2 , ZnO/CdTe, ZnO/Ti,TiO 2 , GaN, and Ga 2 O 3 . [9][10][11][12][13][14][15] In order to fabricate photodetectors, expensive or complex photolithography and vacuum processes are required, which limits their application and environment for general users. To address this limitation, dispensing methods, such as airbrush spray and the spray pyrolysis process, were introduced to form Ag nanowire and carbon a Authors to whom correspondence should be addressed: shju@kgu.ac.kr 2158-3226/2016/6(4)/045218/7 6, 045218-1 © Author(s) 2016.…”

We report on a flexible ultraviolet (UV) photodetector fabricated using an all-spray-coating process. Two spray coating units were utilized to deposit semiconducting tin oxide nanowires as an active channel layer and metallic silver nanowires as an electrode layer. The device was mounted on the back of a human hand, and the UV intensities in sunlight were monitored over time. The fabricated flexible UV photodetector showed highly sensitive, stable, and reproducible detection properties. The main advantage of the proposed fabrication method is the extension of the integration environment by allowing direct application on various substrates, such as clothes and human skin, with varying device size and shape.
