The phrase "as a functional layer" is correct and usable in written English.
It can be used in contexts where you are describing a component or aspect of a system that serves a specific purpose or function.
Example: "In the architecture of the software, the database acts as a functional layer that manages data storage and retrieval."
Alternatives: "as a functional component" or "as a functional element".
It was demonstrated that C3N can be used as a functional layer for optoelectronic devices.
Two Resistive Random Access Memory (RRAM) devices were designed with the thin Al2O3/thick HfO2 stack as a functional layer.
This indicated that the solid case acted as a functional layer to provide further protection and decoration of the porous structure.
In this PEC immunosensor, the PDA thin film serves simultaneously as a unique sensitizer for charge separation as well as a functional layer for probe antibody attachment.
A new affect system was also developed using an existing theoretical framework to serve as a functional layer between some of the physiological and cognitive representations.
It is also useful to include some theory of affect and emotion to act as a functional layer between some representations of physiology and cognition.
A novel fuel-to-electricity conversion technology resembling a fuel cell has been developed based on the perovskite solar cell principle using a perovskite, e.g. La0.6Sr0.4Co0.2Fe0.8O3−δ and an ionic nanocomposite material as a core functional layer, sandwiched between n- and p-conducting layers.
The use of oxygen-containing functional groups of GO as an amphiphilic functional layer improves the wettability of the perovskite precursor solution, which improves the surface coverage and grain uniformity of the perovskite film.
