Abstract:
One example provides a fluidic die including a semiconductor substrate, and a nozzle layer disposed on the substrate, the nozzle layer having a top surface opposite the substrate and including a nozzle formed therein, the nozzle including a fluid chamber disposed below the top surface and a nozzle orifice extending through the nozzle layer from the top surface to the fluid chamber, the fluid chamber to hold fluid, and the nozzle to eject fluid drops from the fluid chamber via the nozzle orifice. An electrode is disposed in contact with the nozzle layer about a perimeter of the nozzle orifice, the electrode to carry an electrical charge to adjust movement of electrically charged components of the fluid.
