What are the Different Types of DOS in Nanostructures?
In nanostructures, the DOS can take various forms depending on the dimensionality of the system:
0D (Quantum Dots): The DOS consists of discrete energy levels, similar to atomic orbitals. 1D (Nanowires): The DOS exhibits step-like features, with sharp increases at certain energy levels. 2D (Quantum Wells): The DOS is constant for each sub-band, resembling a staircase. 3D (Bulk Materials): The DOS is a continuous function of energy, typically following a square-root dependency for simple metals and semiconductors.
