Stepwise fabrication procedure
Oxygen Control
To reliably remove organic constituents without oxidizing ZnSe, we deployed an Arduino-controlled dual-MFC setup (O₂(Air)/N₂). The controller actuates the two MFCs to prescribe the oxygen mole fraction and independently set the overall volumetric flow, enabling low-O₂ thermo-oxidative burnout under controlled residence time and sweep conditions.
