Examining two-dimensional Fröhlich model and enhancing the electron mobility of monolayer InSe by dielectric engineering

In polar compounds, Fröhlich interaction plays an important role in electrical transport, and it is highly dependent on the dimensionality. In two-dimensional (2D) materials, Fröhlich interaction cannot be correctly described by the analytical model available for bulk materials, which prevents the e...
