The electronic properties of monolayer two-dimensional are strongly influenced by the presence of a perpendicular electric field (), finite temperature (), an externally applied spin-polarized exchange field (), and spin-valley coupling effects () induced by surface adatoms or magnetic proximity interactions with a ferromagnetic substrate. Within the framework of the Random Phase Approximation (RPA), we investigate how these external fields reshape electron–electron interactions and provide both analytical and numerical results for the density of states (DOS), quantum capacitance, and effective Fermi velocity. Our findings show that the interplay between , , and leads to the emergence of a spin-valley coupling dependent self-energy structure in the charge carriers, resulting in pronounced spin- and valley-polarized behavior of the effective Fermi velocity. Our predictions agree well with available experimental data and reveal that the Fermi velocity can be tuned via spin polarization, enriching the qualitative and quantitative understanding of quantum effects in these materials.
