Released All-Porous-Silicon Microstructure For Spectrometer Applications
2018 CONFERENCE ON OPTOELECTRONIC AND MICROELECTRONIC MATERIALS AND DEVICES (COMMAD)(2018)
Abstract
All-porous-silicon microstructures have been released with in-situ controllable current density to achieve low residual stress and out-of-plane stress gradient in the porous silicon (PS) films. Optical transmission of large area released PS structures was investigated through both Fourier-transform infrared spectroscopy (FTIR) and modelling in the near infrared and mid infrared wavelength range.
