Tunable Complete Optical Absorption in Multilayer Structures Including Ge sub(2)Sb sub(2)Te sub(5) without Lithographic Patterns

Perfect light absorption over wide angles is possible in a multilayer structure, including Au or Ni metal and Ge sub(2)Sb sub(2)Te sub(5) (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...

Description
Summary:Perfect light absorption over wide angles is possible in a multilayer structure, including Au or Ni metal and Ge sub(2)Sb sub(2)Te sub(5) (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.
