Low-dimensional II-VI semiconductor nanostructures of ternary alloy and transition metal ion doping: Synthesis, Optical properties and Applications

Abstract

Light matter interaction for spin-controlled devices has gained lot of attention in past few years also known as dilute magnetic semiconductor. Strong electron-phonon interaction and outstanding excitonic behavior of II-VI semiconductor is an advantage over III-V semiconductors especially for low dimensional system. Herein, we comprehensively review the spin-exchange interaction of transition metal ion doping through sp-d exchange that enhance the possibility of spin-based photonic in binary, ternary alloy and transition metal ion doping in II-VI semiconductor. For one-dimensional structure, few number magnetic ions can ferromagnetically coupled to form exciton magnetic polaron to give coherent spin-polarized emission, which opens a new horizon to develop bandgap tunable, active waveguide, tunable emission and lasing at nanoscale based on different structures, composition, morphology as well as excitation conditions. The photonic crystal supplies significant information about photon-exciton interactions in the coupled optical microcavities. Lastly, we extend the discussion to the most recent advancement of one-dimensional structure for device application and possible prospective in future technology.
