Aluminum (2 of 2)

Caption: When an electromagnetic wave (left) hits a nanomatryushka (center and right) -- a solid core inside a hollow shell -- the size of the gap determines the strength of the plasmonic response. If the gap is sufficiently small, quantum tunneling through the gap allows plasmons to resonate as though the core and shell are a single particle, dramatically changing their response.
