Electrical and optical studies of Ga-doped ZnO thin films

Fabrication and Characterization of Zinc Oxide-Based Electrospun Nanofibers for Mechanical Energy Harvesting

“…The NGs were subjected to a compressive cyclic load (loading and unloading) of 0.5 kg for 3 s per cycle, representing a load corresponding to a weak finger tap [27]. For determining power, the output voltage was measured for various external resistances (R) ranging from 0 to 10 MX during the excitation process.…”

“…A study of these properties and their dependence is very important to realize better NGs. One way to improve the properties of piezoelectric-based devices is by changing their morphology, e.g., microcantilevers [13], functionally graded materials [24], thin films [15,[25][26][27][28], nanorods [10,29], and nanobelts [14]. Nanofiber structures are significantly different from microscale or macroscale structures, particularly with regard to the high active areas of the former [30].…”

Influence of RF power on the opto-electrical and structural properties of gallium-doped zinc oxide thin films

“…The undoped ZnO has a high resistivity due to a low carrier concentration. To improve its structural, optical and electrical properties, ZnO can be doped with various group-III metals such as aluminum (Al), indium (In), boron (B) and gallium (Ga) [8][9][10]. From many researches related to doping effect of impurities on ZnO, it is widely reported that Al and Ga are the best dopants for ZnO [11].…”

Cation distribution and photoluminescence properties of Mn-doped ZnGa2O4 nanoparticles

“…Cathodoluminescent phosphors have been widely investigated because they have applications in many fields, such as vacuum fluorescent displays (VFD) and field-emission displays (FEDs) [1][2][3]. Among these materials, the ZnGa 2 O 4 phosphor has been studied for its good luminescent characteristics at low voltage region [4,5].…”
