Whenever a compound crystal is cut normal to a randomly chosen direction, there is an
overwhelming probability that the resulting surface corresponds to a polar termination and is …

In this work, piezoelectric ZnO microwire was utilized to form heterojunctions with perovskite
as flexible photovoltaic devices, and has a power conversion efficiency of 0.0216%. By …

Tremendous work has been made recently to improve the power conversion efficiencies
(PCEs) of perovskite solar cells (PSCs); the best reported value is now over 23%. However …

The excitonic light emission of ZnO films have been investigated by means of
photoluminescence measurements in ultraviolet-visible region. Exciton confinement effects …

PIC have been investigated for decades to process information imposed on optical signals
as an essential component for fiber-optic communications,[1] biomedical technology,[2] …

Advances in electron-based instrumentation have enabled the acquisition of
multidimensional data sets for exploring the unique structure–property relationship of …

The crystal orientation and piezoelectric properties of solution grown ZnO nanorods on Ag
films were measured by quantitative piezoelectric force microscopy (PFM). The polarity of …

Polarity is known to affect the growth and properties of ZnO single crystals and epitaxial
films, but its effects are mostly unknown in ZnO nanorods. To leave polarity as the only …

Surface nitridation is used to eliminate O-polar inversion domains and control the growth of
single-domain Zn-polar ZnO film on sapphire (0001) substrate by rf-plasma-assisted …

Al-doped ZnO (AZO) thin films of thicknesses 5, 10, 15, 20, and 30 nm were deposited on
500 eV argon ion-beam fabricated nanoscale self-organized rippled-Si substrates at room …
