“…Most of the 115 In SSNMR studies reported to date have largely focused on indium materials which are used (or have the potential to be used) as semiconductors or conductors. [33][34][35][36][37][38][39][40] Many of these studies report indium Knight shis, sometimes the quadrupolar parameters, and rarely, the chemical shi (CS) tensor parameters. In addition, most of these studies deal with indium materials in which In is in the +3 oxidation state and/or exists in highly symmetric environments.…”

115 In solid-state NMR (SSNMR) spectroscopy is applied to characterise a variety of low oxidation-state indium(I) compounds. 115 In static wideline SSNMR spectra of several In(I) complexes were acquired with moderate and ultra-high field NMR spectrometers (9.4 and 21.1 T, respectively). 115 In MAS NMR spectra were obtained with moderate and ultra-fast (> 60 kHz) spinning speeds at 21.1 T. In certain cases, variable-temperature (VT) 115 In SSNMR experiments were performed to study dynamic behaviour and phase transitions. The indium electric field gradient (EFG) and chemical shift (CS) tensor parameters were determined from the experimental spectra. With the aid of first principles calculations, the tensor parameters and orientations are correlated to the structure and symmetry of the local indium environments. In addition, calculations aid in proposing structural models for samples where single crystal X-ray structures could not be obtained. The rapidity with which high quality 115 In SSNMR spectra can be acquired at 21.1 T and the sensitivity of the 115 In NMR parameters to the indium environment suggest that 115 In SSNMR is a powerful probe of the local chemical environments of indium sites. This work demonstrates that 115 In NMR can be applied to a wide range of important materials for the purpose of increasing our understanding of structures and dynamics at the molecular/atomic level, especially for the characterisation of disordered, microcrystalline and/or multi-valence solids for which crystal structures are unavailable.

“…NMR spectra reveal 2 types of structural distortions in the nearest surroundings of the In atoms. 224 A pressure (P)-induced evolution of magnetism and superconductivity (SC) in a helical magnet CeRhIn 5 with an incommensurate wave vector Qi = ((1)/ (2),(1)/(2),0.297) through the 115 In NQR measurements under P was reported. Systematic measurements of the 115 In NQR spectrum reveal that the commensurate antiferromagnetism (AFM) with Qc = ((1)/(2),(1)/(2),(1)/ (2)) was realised above PmE1.7 GPa.…”

Studies of inorganic semiconductors by solid-state NMR vary widely in terms of the nature of the samples investigated, the techniques employed to observe the NMR signal, and the types of information obtained. Compared with the NMR of diamagnetic non-semiconducting substances, important differences often result from the presence of electron or hole carriers that are the hallmark of semiconductors, and whose theoretical interpretation can be involved. This review aims to provide a broad perspective on the topic for the non-expert by providing: (1) a basic introduction to semiconductor physical concepts relevant to NMR, including common crystal structures and the various methods of making samples; (2) discussions of the NMR spin Hamiltonian, details of some of the NMR techniques and strategies used to make measurements and theoretically predict NMR parameters, and examples of how each of the terms in the Hamiltonian has provided useful information in bulk semiconductors; (3) a discussion of the additional considerations needed to interpret the NMR of nanoscale semiconductors, with selected examples. The area of semiconductor NMR is being revitalized by this interest in nanoscale semiconductors, the great improvements in NMR detection sensitivity and resolution that have occurred, and the current interest in optical pumping and spintronics-related studies. Promising directions for future research will be noted throughout.
