WebApr 20, 2024 · Based on the first-principles, the most stable monolayer graphene and MoS 2 were obtained through the convergence test. The accuracy of their models was verified. In addition, lattice matching mechanisms, stacking modes, electronic structures, and optical properties of the designed heterojunction structures were calculated. In philosophy "first principles" are from first cause attitudes commonly referred to as a priori terms and arguments, which are contrasted to a posteriori terms, reasoning or arguments, in that the former is simply assumed and exist prior to the reasoning process and the latter are deduced or inferred after the initial reasoning process. First principles are generally treated in the realm of philosophy known as epistemology, but are an important factor in any metaphysical speculation.
