Why n and p type semiconductors are electrically neutral
n-p-n
p-type majority carriers are holes n-type majority carriers are electrons
Examples of P-Type Impurities are Boron,Indium and Gallium arsenide Examples of N-Type Impurities are Antimony,Phosphurus
diff. that in n channel & p channel two p type slab in fabricated n type semiconductor & vice -versa
ZnO has an n-type character because of presence of nonstoichiometry that is absence of elemental composition that can be represented by a ratio of well-defined natural numbers.This n-type behaviour is due to point defects like vacancies and interstitials in the ionic crystal. An alternate reason presented , based on theoretical calculations is the unintentional substitutional hydrogen impurities in the compound.
ZnO is the chemical formula of the zinc oxide.
H2SO4 + ZnO => H2O + ZnSO4
Zinc Oxide. Additional answer Except that you won't find ZnO in the periodic table because that table is a table of only the elements and ZnO is a compound, not an element.
Zn+ H2O ---> ZnO + H2 Zn+ H2O ---> ZnO + H2
2 Zn + O2 = 2 ZnO (zinc oxide, a white powder)
There are five
ZnO, SO2 andBeF2 aremolecular formulas.
CO to ZnO. The oxygen (O) stays the same but the carbon (C) changes to Zn
That would be zinc oxide.
on heating,free electrons occupy spaces created by loss of oxygen from zno and turn yellow :)
If you want to balance the equation, then: 2Zn + O2 --> 2(ZnO)
