Solid state devices.
Yes,silicon and germanium are semiconductors.
Slicon (A+) -R.E.M.
Direct band semconductors are mostly for LEDs. Indirect band semiconductors like Si and Ge are conventional diodes.
Non degenerate semiconductors are those which: -are lightly doped -have less value of electron and hole concentration -violate Pauli's exclusion principle Degenerate semiconductors are those which: -are highly doped -have high value of electron and hole concentration -follow Pauli's exclusion principle
Group 14 elements, mainly silicon or germanium are semiconductors. If they are dopped with group 13 elements such as gallium / indium or with group 15 elements such as arsenic / antimony, then the conducting ability increases.

Silicon and germanium are among the widely used semiconducting elements.

semiconductors
P type semiconductors have been doped with trivalent elements, causing them to conduct via "hole" flow. N type semiconductors have been doped with pentavalent elements, causing them to conduct via electron flow.

Metalloids or semiconductors
The semiconductors are found primarily in the transition metals groups and are referred to as metalloids.
