Abstract

A thermoplasmonic device includes a titanium film and a plurality of titanium nitride tube elements disposed on the titanium film. Each of the titanium nitride tube elements includes an open top and a titanium nitride bottom. Each of the titanium nitride tube elements has titanium nitride tubular middle portion that extends from the open top to the titanium nitride bottom.

First claim
