   α-Ga 2 O 3 has the corundum structure analogous to that of α-Al 2 O 3 . The bandgap energy of α-Ga 2 O 3 is 5.3 eV and is greater than that of β-Ga 2 O 3 , making the α-phase attractive for devices that benefit from its wider bandgap. The O–H and O–D centers produced by the implantation of H + and D + into α-Ga 2 O 3 have been studied by infrared spectroscopy and complementary theory. An O–H line at 3269 cm −1 is assigned to H complexed with a Ga vacancy (V Ga ), similar to the case of H trapped by an Al vacancy (V Al ) in α-Al 2 O 3 . The isolated V Ga and V Al defects in α-Ga 2 O 3 and α-Al 2 O 3 are found by theory to have a “shifted” vacancy-interstitial-vacancy equilibrium configuration, similar to V Ga in β-Ga 2 O 3 , which also has shifted structures. However, the addition of H causes the complex with H trapped at an unshifted vacancy to have the lowest energy in both α-Ga 2 O 3 and α-Al 2 O 3 .

   Joint photoelectron spectroscopy and first-principles theory investigations indicate that the Pb-doped PbB₂(BO)_n⁻clusters (n= 0−2) undergo a transformation from σ + π doubly aromatic triangle PbB₂⁻to PbB₄(BO)₂^−/0complexes with a B≡B triple bond.
