Multi-quantum dots control electron occupation numbers through the use of external electric fields, which can be applied using electrodes placed near the dots. By adjusting the strength and direction of these electric fields, the number of electrons in each dot can be controlled.
Coulomb blockade is a quantum phenomenon that occurs when the energy required to add or remove an electron from a quantum dot is greater than the thermal energy of the system. This phenomenon helps to control the number of electrons in a multi-quantum dot by preventing electrons from entering or leaving the dot unless the external electric field is strong enough.
Yes, it is possible to control the occupation numbers of individual dots within a multi-quantum dot system. This is achieved by using separate electrodes and applying different electric fields to each dot, allowing for precise control over the number of electrons in each dot.
Yes, there are some challenges in controlling electron occupation numbers in multi-quantum dots. These include the need for precise control over electric fields, as well as the effects of quantum tunneling and thermal fluctuations, which can impact the accuracy of occupation number control.
The ability to control electron occupation numbers in multi-quantum dots has potential applications in quantum computing, where electrons can be used as qubits for information processing. It can also be used in the development of new types of electronic devices, such as high-speed transistors and sensors.
