Study of transport properties of copper/zinc-oxide-nanorods-based Schottky diode fabricated on textile fabric

Abstract

In this work, a copper/zinc-oxide (ZnO)-nanorods-based Schottky diode was fabricated on the textile fabric substrate. ZnO nanorods were grown on a silver-coated textile fabric substrate by using the hydrothermal route. Scanning electron microscopy and x-ray diffraction techniques were used for the structural study. The electrical characterization of copper/ZnO-nanorodsbased Schottky diodes was investigated by using a semiconductor parameter analyzer and an impedance spectrometer. The current density-voltage (J-V) and capacitance-voltage (C-V) measurements were used to estimate the electrical parameters. The threshold voltage (V th ), ideality factor (η), barrier height (φ b ), reverse saturation current density (J s ), carrier concentration (N D ) and built-in potential (V bi ) were determined by using experimental data and (simulated) curve fitting. This study describes the possible fabrication of electronic and optoelectronic devices on textile fabric substrate with an acceptable performance.

A novel investigation on carbon nanotube/ZnO, Ag/ZnO and Ag/carbon nanotube/ZnO nanowires junctions for harvesting piezoelectric potential on textile

“…All the existing peaks in the XRD spectrum are designated to the specific crystal planes such as (100), (002), (101), (102), (110), (103), (200), (112), and (201) are associated with the hexagonal wurtzite structure of ZnO NWs. 29,31 One additional peak associated to CNTs is present in the graph. Another XRD spectrum (black) is showing the diffraction peaks associated with the hexagonal wurtzite structure of ZnO along with two additional peaks associated with silver (Ag).…”

“…32 Similarly, in all curves the most intense peak was the (002) indicated that the growth orientation is along the c-axis. [27][28][29]31 A piezoelectric potential is generated when the ZnO NWs are bent by the AFM tip and the mechanical energy from this action induces an electric field along the direction of applied force due to the lattice deformation in the NWs. The mechanical energy is then transformed into electrical energy when the AFM tip and the NWs are in forward bias.…”

Analysis of direct and converse piezoelectric responses from zinc oxide nanowires grown on a conductive fabric

“…The fabric was cleaned by ultrasonic bath in isopropanol, acetone and deionized water, and then dried with nitrogen air pressure. The most common low temperature, environment friendly, economic and simple ACG method was used for the growth of ZnO NWs, as reported in our previously published articles . Ammonia solution 25% was added for controlling the diameter of grown ZnO NWs and increasing the growth rate .…”

“…Ammonia solution 25% was added for controlling the diameter of grown ZnO NWs and increasing the growth rate . Prior to the growth of ZnO NWs, a seed solution containing ZnO nanoparticle was prepared by dissolving zinc acetate in methanol and was deposited on the textile substrate by spin coating at a speed of 4000 rpm.…”

“…This process was repeated three times to achieve a homogeneous seed layer of ZnO particles on the substrate surface. The seeded substrate was then heated at 100 °C for 10 min as described previously . After the growth of ZnO NWs, the sample was rinsed with isopropanol and deionized water for removing the unwanted residues and then dried by nitrogen air pressure.…”
