“…For achieving such applications, one of the most important goals is to obtain high quality ZnO films homoepitaxially grown on the ZnO single crystal substrates. There are several methods to grow large scale ZnO single crystals, such as hydrothermal methods [3][4][5][6], the chemical vapor transport methods [7], melt growth [8,9] and molten salt method [10,11]. Among them, hydrothermal methods and the chemical vapor transport methods are not feasible currently, because their growths are slow and their equipments are complicated.…”

a b s t r a c tThe subsolidus phase relations of the ternary system ZnO-B 2 O 3 -V 2 O 5 were investigated by means of X-ray diffraction (XRD). There is no ternary compound in the system. There are seven binary compounds which have been reported in the ZnO-B 2 O 3 -V 2 O 5 system, which can be divided into eight 3-phase regions. The phase diagram of Zn 4 V 2 O 9 -Zn 3 B 2 O 6 pseudo-binary system from 740 • C to 1250 • C has also been constructed through XRD and differential thermal analysis (DTA) methods, and the result reveals this system is eutectic system. The eutectic temperature is 780 • C and eutectic point comprises 55% Zn 4 V 2 O 9 and 45% Zn 3 B 2 O 6 . The mixture with the composition near the eutectic point might be the suitable flux for ZnO crystal growth.

“…This is considered to be one of the reasons why xylene can be decomposed under irradiation by visible light by the fiber, as described in the introduction of this paper. ZnO is essentially a direct-gap semiconductor with a wide bandgap of 3.37 eV [11]. The ZnO fibers described here have the ability to respond to visible light; thus the formation of new energy levels can be considered.…”

“…These were grown with the hydrothermal (HDT) method, 24) the seeded chemical vapor transport (SCVT) method, 25) or the flux method. 26) Samples made from these single crystals were used to evaluate the effect of donor concentrations in the ZnO crystal on the electrical properties of the resultant sandwich structures.…”

As part of an effort to develop low-voltage surge filters, zinc oxide (ZnO) bicrystals were investigated to clarify the electronic state of grain boundaries in ZnO varistors. The varistors had a ZnO/glass/ZnO-type sandwich structure, and the interfacial glass layer was composed of oxide glass of the Bi-B-O system. A highly nonlinear current-voltage relationship was obtained for a sandwich structure composed of Co-doped single crystal ZnO, and the current through the junction was proportional to roughly the 30th power of the bias voltage at the breakdown stage. In contrast, the junction using undoped single crystal ZnO showed insignificant nonlinearity. Dielectric measurements revealed that a double-sided depletion layer was formed at the interface and the high nonlinearity was ascribed to the corresponding potential barrier formed at the interface.
