Today's technology is limited, not by the electronics, which are already "really powerful," but because the interface between the brain tissue and the electronics is far from ideal, says Charles Lieber, a professor of chemistry and chemical biology at Harvard University.
But the layered structure of the nanotubes lays down a blueprint for converting light into electricity, because the interface between the donor and acceptor layers can be thought of as a p-n junction, the basic unit of a solar cell, says Frank Wurthner, a chemistry professor at the University of Wurzburg, in Germany.
However, the coefficient of thermal expansion (CTE) mismatch between copper and Si has always been a troublesome problem and the primary disadvantage of using a copper baseplate because the interface between the substrate and the heat spreader is one of the main failure sources of a power module.
Because the interface between the hybrid layer and adhesive resin is relatively stronger than the hybrid layer itself, the hybrid layer is more prone to defect formation.
Likewise, in Figure 11 for the female pelvis, because the interface between the perineal membrane and the LA was difficult to draw, the LA is shifted from the actual superoposterior side of the perineal membrane to the posterior side.
Meanwhile, because of the interlayer sliding, the interfaces between the atomic layers become incommensurate and the increased interfacial energy can be calculated as, where γint=0.11 N m−1 is the interfacial energy constant, L is the length of the sliding interface and c is the lattice constant along the sliding direction.
Because the electromagnetic field at the interfaces between two layers satisfies boundary conditions, the vectors of the transmission amplitude can be calculated by the S-matrix which relatesasub andbair toaair andbsub as [19] a sub b air = S a air b sub ≡ S 11 S 12 S 21 S 22 a air b sub.
