p-Type zinc oxideX-ray photoelectron spectroscopyThe valency of Sb changed from Sb3+ to Sb5+ in ZnO grown by MOCVD with increasing mole ratio of Sb precursor to Zn precursor.The conductivity type of Sb doped ZnO was also changed from p-type to n-type accordingly.The p-type ZnO was ...
Located in the middle section of the periodic table, the transition metals are elements that often have more than one oxidation state and can combine with other elements in different ways to form different compounds. For example, iron can form both iron (II) oxide and iron (III) oxide, whic...
