Nanoscale devices, such as quantum dots and nanowires, are significantly influenced by Coulomb interactions:
Quantum Confinement: In quantum dots, Coulomb interactions between electrons and holes affect the optical and electronic properties, leading to size-dependent behaviors. Single Electron Transistors (SETs): In SETs, the Coulomb blockade effect arises due to the electrostatic energy required to add an extra electron, enabling precise control of electron transport at the nanoscale. Nanowire FETs: The behavior of nanowire-based field-effect transistors (FETs) can be tailored by manipulating the Coulomb interactions, impacting their performance and scalability.
