Based on all the above results, the growth kinetics of B doped Si 1-xGex(001) GS-MBE were modeled. Film deposition rates RSiGe decrease by ≈50% with increasing CB ≥ 5 x 1019 cm-3 at Ts = 500°C. The TPD results ...

We have studied the energy spectrum of multiwall carbon nanotubes using differential conductance measurements. The carbon nanotubes act as the Coulomb island of a single electron tunneling transistor. Temperature dependence ...

A study of the decay D*+ ---+ (K- 1r+ ) 1r+ (and charge conjugate) has been performed based on data taken from n-nucleus collisions by the experiment E400 at the Proton East area of FNAL. A signal was observed at the ...

Production of the charmed baryon Ac has been observed in n-nucleus collisions at the Proton East area of FNAL. A 50' peak was seen in the decay mode At -+ pK-7r+ (and charge congugate). The lifetime was determined to be ...

We have investigated the influence of zinc doping on the Hall effect in detwinned and twinned single crystals of $\rm YBa\sb2Cu\sb3O\sb{7-\delta}$. We observed the sign reversal of the Hall effect for crystals with ...

We measured the Hall effect in untwinned single-crystal YBa$\sb2$Cu$\sb3$O$\sb{\rm 7-y}$, a high-T$\sb{\rm c}$ superconductor. The crystals were grown using a technique that we invented, in which untwinned domains are ...
