Structural and optical properties of sputtered ZnO thin films

An electrochemical DNA biosensor based gold-thiolate conjugation utilizing ruthenium complex [Ru(dppz)2(qtpy)]Cl2

“…8a), the highest intensities of the crystal growth orientation appeared on (002) plane, which was located at 34.66°, followed by other standard ZnO peaks. The XRD result clearly showed that the diffraction peaks fit well with the hexagonal wurtzite structure of the ZnO NRs (Flickyngerova et al 2008;Kashif et al 2013b). The sharp and narrow diffraction of the peaks of all ZnO demonstrated that the hydrothermal derived ZnO NRs were synthesized with high crystallinity.…”

High-rate, room temperature plasma-enhanced deposition of aluminum-doped zinc oxide nanofilms for solar cell applications

“…In the magnetron sputtering process, high growth rates are usually achieved by process operation at high target powers [25,26]. However, under such conditions, energetic species arriving at the substrate usually affect film properties such as hardness, adhesion strength, structure, optical properties and sometimes even lead to deterioration of the film quality.…”

Synthesis of ZnO:N thin films by reactive dc magnetron sputtering

“…The synthesis of n-type ZnO of low resistivity by doping with Al was already demonstrated by many authors [2,3]. Unfortunately the lack of viable p-type doped ZnO prevents development of LEDs based on p-n homojunction despite many studies of ZnO for LEDs application [6].…”

“…ZnO thin films and nanostructures have been investigated for a long time as a very promising material for piezoelectric [1], gas sensing [2], transparent conducting oxides [3], for spintronics [4], ultra-violet (UV) light-emitting diodes (LEDs) [5], and other applications. The main reasons why ZnO is suitable for LEDs application are the wide band gap of 3.37 eV at room temperature and an extremely large free exciton binding energy of 60 meV, which allows excitonic emission even at room temperature and above in near UV spectral region [5,6].…”
