Choose the options that would form a p-type semiconductor. Choose all that would make a p-type semiconductor, there may be more than one. Antimony doped with Germanium Germanium doped with Phosphorus Tin doped with Arsenic Silicon doped with Aluminum Arsenic doped with Tellurium

Silicon (Si) and germanium (Ge) can be used as semiconducting materials. The band gap between the conduction band and valence band is measured in electron volts, eV. 1 eV = 1.6022 × 10⁻¹⁹J. The band gap of each semiconductor was measured, and the two values were found to be 0.69 eV and 1.12 eV. Which of the two values belongs to Ge? A) 0.69 eV B) 1.12 eV C) Cannot be determined without further information.

Graphite has a layered structure, with each layer made up of six-membered rings of carbon fused with other similar rings on all sides. The Lewis structure shows alternating single and double bonds. Diamond is an insulator, and graphite is a moderately good conductor. Explain these facts in terms of the bonding in each. (Conductance of graphite is significantly lower than metals but is higher than most nonmetals.) What behavior would you predict for carbon nanotubes, the cylindrical form of fullerenes?
