In the context of physical systems, 3-dimensional systems are systems whose relevant degrees of freedom are embedded in or constrained by three spatial dimensions, typically described by coordinates (x, y, z) in Euclidean space. Their behavior is governed by field equations or dynamical laws defined over a 3D manifold, such as Maxwell’s equations, Navier–Stokes equations, or Schrödinger’s equation in three spatial dimensions. These systems exhibit phenomena inherently dependent on 3D geometry and topology, including volumetric interactions, three-component vector fields, and spatially resolved boundary conditions, and they often require tensorial or vector calculus formalisms for accurate modeling and analysis.
A technology enabling the fabrication of intricate three-dimensional (3D) quantum dot (QD)-based structures at room temperature has been developed.
