“…Moreover, a non-toxic and inexpensive ZnO with a stable wurtzite structure doesn't only has a high transparency in the visible light region but it has also a direct wide band gap of 3.37 eV at room temperature which makes it one of the most encouraging materials for potential applications in various fields such as optoelectronic devices, transparent electrodes of solar cells, liquid crystal displays, memristors and gas sensing [15][16][17][18][19].…”

The modification and tailoring the characteristics of nanostructured materials are of great interest due to controllable and unusual inherent properties in such materials. A simple spray pyrolysis technique is used to prepare pure and La-doped ZnO films. The influence of La concentration (0, 0.33, 0.45, 0.66, 0.92 and 1.04 at. %) on the structural, optical, and magnetic properties of ZnO was investigated. The exact nominal compositions of the prepared films were determined from the field emission scanning electron microscope occupied with EDX. X-ray diffraction confirmed that the samples possessed single-phase hexagonal wurtzite structure. The main crystal size was decreased from 315.50 Å to 229.04 Å depending on La dopant concentration. This decrease is due to the small ionic radius of Zn ions in compared to La ions.The band gap values were found to be depend strongly on La 3+ ion content. Introducing La into ZnO induces a clear magnetic moment without any distortion in the geometrical symmetry, it 2 also reveals the ferromagnetic coupling. The saturation magnetic moment of 1.04 at% La-doped ZnO shows the highest value of 0.014 emu, which is ~23 times higher than pure ZnO sample.The obtained results were discussed and compared with other literature data and showed an acceptable agreement.

Electronic properties of intrinsic ZnO, N doped ZnO and Al‐N co‐doped ZnO of both hexagonal wurtzite (HW) and zinc blende (ZB) structures were investigated by first‐principles calculations. Both N doped ZB‐ZnO and N doped HW‐ZnO achieve p‐type transition by the introduction of N‐2p states, forming shallow acceptor levels above the valence band. However, the positive impurity formation energy implied the difficulty and instability of N‐doped ZnO. In Al‐N co‐doped ZnO, the Al elements compensate the p‐type doping effect, but partially enhance the solubility of N. Furthermore, the comparison of the electronic properties between HW‐ZnO and ZB‐ZnO, indicated that the ZB structure favors the achieving of p‐type doping.This article is protected by copyright.
