DOI: 10.1016/j.commatsci.2018.07.039
Abstract: Abstract We investigated the optical properties and electronic structure of NV−1 center in diamond and 3C-SiC by combing photoluminescence spectroscopy (PL) and first-principles calculations. The NV−1 center in diamond and 3C-SiC were produced by 10 MeV… read more here.

DOI: 10.1021/acs.nanolett.2c04845
Abstract: We report spin-polarized transient absorption for colloidal CdSe nanoplatelets as functions of thickness (2-6 monolayer thickness) and core/shell motif. Using electro-optical modulation of co- and cross-polarization pump-probe combinations, we sensitively observe spin-polarized transitions. Core-only nanoplatelets… read more here.

DOI: 10.1103/physrevapplied.12.064005
Abstract: Three-dimensional arrays of silicon transistors increase the density of bits. Solid-state qubits are much larger so could benefit even more from using the third dimension given that useful fault-tolerant quantum computing will require at least… read more here.

DOI: 10.1103/physrevb.110.l220302
Abstract: We investigate the spin-coherence decay of NV− spins interacting with the strongly coupled bath of nitrogen defects in diamond layers. For thin diamond layers, we demonstrate that the spin-coherence times exceed those of bulk diamond,… read more here.
