Doping a silicon crystal with sulfur…
...moves the Fermi level closer to the valence band.
...moves the Fermi level closer to the conduction band.
...widens the band gap.
...makes the band gap narrower.
[TRUE/FALSE] Statement A: ONLY semiconductor elements under the 14th group of the periodic table have 4 valence electrons. Statement B: ALL elements under the 14th group of the periodic table have 4 valence electrons.
Only second statement is true
Only second statement is false
Both statements are false
Both statements are true
[TRUE/FALSE] Statement A: When covalent bonds break, electrons will be freed from the lattice, thus the presence of free electrons. Statement B: When covalent bonds do not break, electrons will be locked into the lattice, thus no conduction of electricity.
Both statements are incorrect
Both statements are true
Only the first statement is false
Only the first statement is true
