In physics, 2-dimensional systems are idealized physical systems whose relevant degrees of freedom are confined to a plane or an effectively two-dimensional manifold, such that dynamics and interactions occur predominantly within two spatial dimensions. They exhibit distinct phenomena compared with three-dimensional counterparts, including modified density of states, altered screening and fluctuation behavior, and dimensionality-dependent phase transitions (e.g., Kosterlitz–Thouless transitions mediated by topological defects). Examples include electrons in quantum wells or at interfaces, ultrathin films, and certain spin or lattice models defined on 2D lattices, which serve as fundamental platforms for studying critical phenomena, topological phases, and low-dimensional quantum many-body effects.
A dissertation study at the University of Jyväskylä (Finland) developed two-dimensional fishnet-like structures from DNA origami for silicon surfaces and investigated how different conditions affect their formation. The results ...
