LIGHT-EMITTING DIODES THERE IS LIFE OUTSIDE OF SILICON  

In contrast, the anode is usually tin-doped In203 (ITO, typically 1 9 Sn In), since this material is transparent and highly conductive ca. 1 x 10 cm ). The sub-

Thus far, we have considered the structure and applications of Si - the most heavily employed semiconductor. It should be noted that gallium arsenide (GaAs) is also widely used for FET applications since GaAs does not form a natural protective 

The substitutional replacement of In ions with Sn ions results in n-doping of the lattice, injecting electrons into the conduction band. The doping of Sn into the In20s lattice may also result in SnO sites this introduces holes in the lattice that reduces its conductivity. The conductivity of ITO is due to both Sn dopants and O vacancies, as represented by the general formula fri2 cSn Os Since the
