The advent of 2D ferroelectrics, characterized by their spontaneous polarization states in layer-by-layer domains without the limitation of a finite size effect, brings enormous promise for applications in integrated optoelectronic devices. Comparing with semiconductor/insulator devices, ferroelectric devices show natural advantages such as non-volatility, low energy consumption and high response speed. Several 2D ferroelectric materials have been reported, however, the device implementation particularly for optoelectronic application remains largely hypothetical.

- GPAW is a powerful, open-source Python program for studying how electrons behave in materials using a method called density functional theory (DFT).
- It can use different ways to represent these electron states, making it very flexible compared to other similar programs.
- GPAW can also do advanced calculations for things like excited states, magnetic properties, and has recently added support to work faster with special computer hardware called GPUs.
