The physical phenomena governing hyperpolarization through optical pumping of conduction electrons continue to be explored in multiple semiconductor systems. One early finding has been the asymmetry between the optically pumped nuclear magnetic reson

We have measured the 75As signals arising from the interface region of single-crystal semi-insulating GaAs that has been coated and passivated with an aluminum oxide film deposited by atomic layer deposition (ALD) with optically pumped NMR (OPNMR). U

Solid-state 71Ga NMR was used to characterize a series of [Ga13(μ3-OH)6(μ2-OH)18(H2O)](NO3)15 “Ga13” molecular clusters synthesized by multiple methods. These molecular clusters are precursors to thin film electronics and may be employed in ene

Solid-state 71Ga and 69Ga NMR was used to probe the structure of the hydroxo-aquo cluster, [Ga13(μ3-OH)6(μ2-OH)18(H2O)24](NO3)15, envisioned as a solution-processable material for thin film electronics. This species, termed Ga13, is made up of thre

1H and 27Al NMR is used to reveal the motions of AlH4 anions in KAlH4. Line-narrowing from rotations and from translational diffusion is observed in the NMR of both nuclei. Unlike the anions in NaAlH4 and LiAlH4 that are not rotating on the NMR time
