The semiconductor ZnO has gained substantial interest in the research community in part
because of its large exciton binding energy (60 meV) which could lead to lasing action …

The polar nature of the wurtzite crystalline structure of GaN and ZnO results in the existence
of a spontaneous electric polarization within these materials and their associated alloys (Ga …

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 …

The p–n junction was invented in the first half of the twentieth century and the latter half saw
the birth of light emitting diodes: red and yellow/green in the 1960s and yellow in the 1970s …

ZnO nanorods (NRs) and nanotubes (NTs) have been synthesized by a hydrothermal
method on Si substrates that had been precoated (by pulsed laser deposition (PLD)) with a …

Zinc oxide (ZnO) has been known as the next most important material for the fabrication of
efficient nanodevices and nanosystems because of its versatile properties such as …

Nitrogen-doped films of ZnO grown by two methods, metalorganic chemical vapor
deposition (MOCVD) and reactive sputtering, were studied with x-ray and ultraviolet …

Ultra-thin ZnO nanowire (NW)/nanotube (NT) arrays have been formed on ZnO film-coated
Si substrates by a hydrothermal growth method. The individual nanostructures are single …

Polar surfaces of compound materials have been the subject of intense activity in the past.
Electrostatic arguments, based on a model of rigid charges, predict that they should have an …

Transparent and conductive Al-doped ZnO (AZO) thin films were deposited on substrates
including alkali-free glass, quartz glass, Si, and SiO2 buffer layer on alkali-free glass by …
