Oxide characteristics
WebZinc oxide (ZnO) is a promising candidate as the ETL for roll-to-roll printed OPVs because it is easily solution-processable, nontoxic, and low-cost. ZnO is an n-type semiconductor with a bandgap of 3.3 eV, electron mobility about 10−4 to 10 −3 cm 2 V −1 S −1 and has been used as ETL in OPV since 1999. ZnO layers can be deposited either ... WebNitric oxide is a colorless, flammable gas with a slight odor. Nitrogen dioxide is a deep red-orange gas that is poisonous but not flammable. It, along with aerosols, is responsible for the reddish-brown color of smog. At high concentrations it is highly toxic, and can cause serious lung damage.

WebAug 21, 2024 · Metals are protected from further oxidation by forming a hard scale of oxides when it is being oxidized. Not all metal oxides form a scale. In general, when the oxide formed is not very dense, it is not under stress, and the oxide layer forms a scale. Usually, a mole of metal oxide should occupy more volume than a mole of the metal itself. WebJan 15, 2024 · Physical Properties of Diamond. has a very high melting point (almost 4000°C).
