A low-cost and highly controllable roll-to-roll templated deposition method for fabricating a nanostructured film comprising: creating a stacked structure comprising a conductive substrate, a porous template disposed on the substrate, an ion-conductive layer formed of a porous scaffold or a polymer gel containing electrolytes disposed on the template, and an anode disposed on the ion-conductive layer; providing rollers on the anode; applying pressure to the stacked structure via the rollers so that the first porous template conforms and stays attached to the substrate; applying galvanic potential between the metal anode and the conductive substrate to grow a nanostructure from the substrate into the porous template by electrochemical deposition; and removing the porous template by chemical dissolution or chemical etching to obtain the nanostructured film. Tube rollers comprising, radially, tubes, electrolytes, and anodes may replace the rollers, electrolytes, and anodes. The nanostructured film may also grow on both sides of the substrate.

This invention discloses a visible light extended InGaAs detector and its fabrication method. According to this method, an internal structure is formed from bottom to top as p... + Type-contact metal electrode, oxide nitride passivation layer, p + Type InP contact layer, n ‑ Type InGaAsP composition graded layer, n ‑ Type InGaAs absorber layer, n + A photoelectric sensor based on a composite antireflective film system of InP contact layer and nanostructure was developed, and InGaAs detectors were fabricated from it, which improved the performance of the device. It can effectively absorb light in the visible to short-wave infrared band. At the same time, by combining layered thin films and nanostructures, the composite antireflective film system was constructed using the effective medium theory and film stack formula. Compared with single-layer substrate nanostructure film layer, it can effectively reduce the surface leakage current of InP contact layer. Compared with traditional layered medium antireflection film, it also has certain wide-spectrum and wide-angle antireflection characteristics.
