Impedance spectroscopy is essential in understanding the physical and chemical processes
that affect theelectronic behavior of semiconducting metal oxide-based gas sensor …

ZnO is one of the most widely studied semiconductors due to its direct wide band gap and
high exciton binding energy. Due to its ease of synthesis, robustness and low cost, ZnO has …

Precise control of morphologies of one-or two-dimensional nanostructures during growth
has not been easy, usually degrading device performance and therefore limiting …

Highly sensitive ethanol sensors are important for environmental and industrial monitoring.
In our work, we demonstrate a method to enhance the response of a Schottky sensor based …

Conventional metal oxide semiconductor (MOS) gas sensors have been investigated for
decades to protect our life and property. However, the traditional devices can hardly fulfill the …

Compared to ZnO-based photoconductive photodetectors (PDs), photovoltaic PDs possess
the advantages of easy fabrication, low dark current, high response speed and possible self …

We in situ probed the surface band bending (SBB) by ultraviolet photoelectron spectroscopy
(UPS) in conjunction with field-effect transistor measurements on the incompletely depleted …

In this research, the low-temperature single-step electrochemical deposition of arrayed ZnO
nanowires (NWs) decorated by Au nanoparticles (NPs) with diameters ranging between 10 …

In this report, ZnO single nanowire (NW)-based devices were fabricated on the same
nanowire by e-beam lithography so that both sides had Ohmic contact and one side had …

Although pyroelectric photodetectors have been intensively studied, the transient
temperature change rate of pyroelectric materials is a main restrictive factor for improving the …
