In several upcoming rheological approaches, including methods of micro- and nanorheology, the measurement geometry is of critical impact on the interpretation of the results. The relative size of the probe...

Diffusion pipes in silicon NPN structures were investigated both by electrical measurements and by microsectioning. It was found that certain crystalline defects, specifically stacking faults and edge dislocations, can act as sites for the formation of such pipes. The presence of gold doping at these lattice defects greatly increases the incidence of pipes, apparently by offering a path of enhanced diffusivity for phosphorus from the emitter.

By analysing the rotational diffusion of nanoprobes, we explore bond strengths and molecular dynamics in metal ion-coordinated transient networks.
