Query: Experimental demonstration of broadband absorption enhancement in
  partially aperiodic silicon nanohole structures   We report the design, fabrication, and optical absorption measurement of
silicon membranes patterned with partially aperiodic nanohole structures. We
demonstrate excellent agreement between measurement and simulations. We
optimize a partially aperiodic structure using a random walk algorithm and
demonstrate an experimental broadband absorption of 4.9 times that of a
periodic array.
