Electronic structure of rare-earth mononitrides: quasiatomic excitations and semiconducting bands

The Role of Rare Earth Dopants in Semiconducting Host System for Spin Electronic Devices

Crystal-field study in rare-earth-doped semiconducting YBiPt

Electron spin resonance ~ESR! and magnetic-susceptibility experiments in the rare-earth-doped (R5Nd, Er, and Yb! cubic semiconducting YBiPt allow estimates of the fourth (A4) and sixth (A6) order crystal-field parameters for this compound. It is found that these parameters are of the same order for all the R studied. On the other hand, no crystal-field effects were found for the Gd doped single...

Coherent storage of microwave excitations in rare-earth nuclear spins.

Interfacing between various elements of a computer--from memory to processors to long range communication--will be as critical for quantum computers as it is for classical computers today. Paramagnetic rare-earth doped crystals, such as Nd(3+):Y2SiO5(YSO), are excellent candidates for such a quantum interface: they are known to exhibit long optical coherence lifetimes (for communication via opt...

Effect of virtual 4d-shell excitations on rare earth spectra

Ab initio energies for electric dipole transitions 4d(S0) → 4d94f J = 1 in triply-ionized lanthanum have been calculated by constructing an effective interaction, acting within the configuration 4d94f, that incorporates effects of virtual 4d-shell excitations to all orders of perturbation. Virtual 4d-shell excitations, included within the random phase approximation, and virtual excitations to s...

ice: Surface structure and electronic excitations

We present a study of the electron-stimulated desorption of deuterium cations ~D ) from thin ~1–40 ML! D 2O ice films vapor deposited on a Pt~111! substrate. Measurements of the total yield and velocity distributions as a function of temperature from 90 to 200 K show that the D yield changes with film thickness, surface temperature, and ice phase. We observe two energy thresholds for cation emi...
