Tunable Complete Optical Absorption in Multilayer Structures Including Ge2Sb2Te5 without Lithographic Patterns

Perfect light absorption over wide angles is possible in a multilayer structure, including Au or Ni metal and Ge2Sb2Te5 (GST) phase change material, without the need of sophisticated lithography. The GST layer also permits deep modulation of the absorption when it undergoes a phase transition.
