Better field emitters from GaZnO nanopagodas

22 Apr 2013

By Wendy Mak, Development Editor.

This article is HOT as recommended by the referees. And we’ve made it free to access for 4 weeks.

ZnO nanostructures have generated much interest recently due to their unique properties, which make them ideal candidates for photo applications such as solar cells, light emitting diodes and field emission displays. While it has been known that Ga doped ZnO shows good field emission properties, there are very few studies on how Ga doping affects the ZnO crystals.

In this paper, the authors investigated Ga doped ZnO nanostructures grown by metal–organic chemical vapor deposition. By varying the growth temperature, Ga concentration and growth time, the authors were able to vary the morphology of the GaZnO nanostructures from wires to a pagoda shape. The formation of the pagodas were also explained via a computational simulation of the growth process.

A study of the field emission properties of the GaZnO nanopagodas demonstrated that the geometry of the nanostructure and the density of the pagodas affects the turn-on voltage of the emitters as well as the field enhancement factor. In general, the nanopagodas demonstrated better field emission properties than pure ZnO nanowires.

This study can guide crystal engineers towards designing and producing better GaZnO nanostructures for practical applications.

This article is HOT as recommended by the referees. And we’ve made it free to access for 4 weeks.

Computational simulations have played an important role in the understanding of crystal structures and the atomic level forces which give them different properties. In this excellent Highlight paper, Professor Angelo Gavezzotti draws on his experience as a theoretical chemist as well as some recent experimental results to illustrate the different techniques one may use to model crystalline substances.

Covering topics such as phase transitions, crystal geometry and intermolecular interactions, it is a must read for anyone interested in computational chemistry.

Precise silver indium disulphide nanocrystals for photodetectors

16 Apr 2013

By Wendy Mak, Development Editor.

This article is HOT as recommended by the referees. And we’ve made it free to access for 4 weeks.

Following on from a previous blog on CuInS₂ nanocrystals, this post is about a very similar material: AgInS₂ nanocrystals! Similar to CuInS₂, AgInS₂also shows desirable properties such as a suitable band gap energy, high absorption coefficient and low toxicity, making them good candidates for optoelectronic devices. As the size and morphology of these crystals determine how they perform, it will be useful to produce nanocrystals with uniform shapes and sizes.

In this paper, a method of synthesising AgInS₂ nanocrystals with a uniform size is presented. The authors also demonstrated a way to vary the size of the crystals by changing the composition of the solvents in which the crystals form. An investigation of the photoelectric properties of the AgInS₂ nanocrystals was carried out, in which the crystal were hybridised with poly (3-hexylthiophene) to form nanodevices. These devices operate as switches, and with their high sensitivity to light, fast response times, and stability to reversal, can be utilised in many photoelectric applications.

Shell extract helps rebuild pearly whites

16 Apr 2013

By Kate Bandoo, Publishing Assistant.

Researchers in China have shown that the organic component of mother of pearl can help repair damaged teeth, by acting as a template for the mineralisation of tooth enamel.

Tooth enamel is made up of rod-like crystals of hydroxyapatite, a calcium phosphate mineral. It is the hardest tissue in the body, but is susceptible to erosion by food and bacterial acids. Once gone, it never naturally reforms, and cavities must be fixed using manmade materials. Methods of artificially rebuilding enamel often involve extreme temperature, pressure or pH conditions that make them impractical for clinical use.

Made to order: controlling the crystal structure of copper indium disulphide nanocrystals

11 Apr 2013

By Wendy Mak, Development Editor.

This article is HOT as recommended by the referees. And we’ve made it free to access for 4 weeks.

CuInS₂ belongs to a class of inorganic semiconductors known as metal chalcogenides, which have desirable optical properties that make them useful in photovoltaics. In solar cell applications, CuInS₂ is usually deposited as nanocrystals, and the size, shape and structure of these crystals determine the properties of the device. Therefore, it will be desirable to have a synthetic method that can produce crystals with a uniform morphology, and to be able to vary this by changing the synthetic conditions.

Jin Chang and Eric R. Waclawik have achieved this by a wet-chemical method in which CuInS₂ forms nanocrystals with a zincblende structure when a weak-coordinating solvent is used, whereas strong-coordinating solvents produce a wurzite structure. The authors were also able to explain the effect by investigating the intermediate species formed during the chemical reaction. This synthetic method was also extended to two other useful materials: Cu₂SnS₃ and Cu₂ZnSnS₄, and they were able to produce pure zincblende or wurzite structures depending on the solvent used.

The synthetic process presented in this paper has the potential to be used in fine tuning the optoelectronic properties of photovoltaic materials, thus yielding better devices for solar energy generation.

Zwitterionic MOF is better for hydrogen storage

03 Apr 2013

By Wendy Mak, Development Editor.

This article is HOT as recommended by the referees. And we’ve made it free to access for 4 weeks.

Metal organic frameworks (MOFs) are porous materials with a high surface area. This makes them useful for processes such as catalysis and gas storage, including hydrogen storage, which is crucial for environmentally friendly energy applications.

Nevertheless, many MOF structures can only hold onto H₂ molecules at very low temperatures and concentrations. To enable the MOF to hold onto H₂ molecules at higher temperatures and concentrations, Lalonde and colleagues have synthesized MOFs with a zwitterionic structure, where the negatively charged Zn₂(CO₂)₅groups are separated from the positive imidazole tetra acid groups. The material shows enhanced H₂ adsorption, and is a good candidate for further optimisation. The zwitterionic design can also be applied to synthesizing other MOF structures or porous materials for use in H₂ storage.
