Summary of science materials doctoral thesis: Fabrication and investigation of characteristics of photonic microcavity 1D for optical sensors

The objectives of the thesis: Research and fabricate the one-dimensional (1D) – nanoporous silicon microcavity (1D-NPSMC) structures by using electrochemical etching method with the selectivity of wavelength in visible range from 200 nm to 800 nm. The 1D-NPSMC structures has high reflectivity, narrow linewidth of the pass-band and homogeneous pores ii) Design the photonic sensor device based on 1D-NPSMC structure which is capable of measuring in two modes: liquid phase (used for determination pesticides) and vapor phase (used for determination organic solvents) iii) Determinate the low concentrations of pesticides and organic solvents in aqueous medium.
