Group 14 elements such as silicon or germanium generally act as semi-conductors. Boron, a group 13 element, normally acts as a dopant in semiconductors.
Boron, B belongs to the semiconductors(metalloids) family. Semiconductors are located toward the right side of the periodic table.

Examples of p-type semiconductors include materials like boron-doped silicon, gallium arsenide, and aluminum gallium arsenide. These materials have a deficiency of electrons, leading to "holes" in the crystal lattice that behave as positive charges.
donor--arsenic, phosphorus, nitrogen acceptor--boron, aluminum, gallium
Fairly certain Beryllium Oxide is an extrinsic semiconductor with band gap 10.6 eV. Otherwise the answer is Boron Nitride (6.36 eV)
Application of semiconductors
Boron is use in doping semiconductors, modifying their electrical properties. Boron oxide (B2O3) is used in glassmaking and ceramics. Borax (Na2B4O7.10H2O) is used in making fiberglass, as a cleansing fluid, a water softener, insecticide, herbicide and disinfectant. Boric acid (H3BO3) is used as a mild antiseptic and as a flame retardant. Boron Nitride's hardness is second only to diamond, but it has better thermal and chemical stability, hence boron nitride ceramics are used in high-temperature equipment. Boron nitride nanotubes can have a similar structure to carbon nanotubes. BN nanotubes are more thermally and chemically stable than carbon nanotubes and, unlike carbon nanotubes, boron nitride nanotubes are electrical insulators. Boron carbide (B4C) is used in tank armor and bullet proof vests.
Transistors are made out of semiconductors, yes.
Semiconductors are 90% of the time made of Silicon, enhanced into P-Type or N-Type depending on needed polarities. P = Positive, N = Negative, Boron gas has excess negative electrons and is used in doping to create N-Type Silicon.
