Hi. Could anyone explain me what is a heterostructure clearly? And when a heterostructure is a quantum well?
A heterostructure is a type of material that is composed of two or more layers of different semiconductor materials. These layers have different bandgaps, which allows for the creation of unique electronic and optical properties.
Heterostructures have a wide range of applications, including in electronic devices such as transistors and lasers, as well as in optoelectronic devices like solar cells and LEDs. They can also be used in quantum computing and sensing technologies.
Heterostructures are typically created using a technique called epitaxy, where layers of different semiconductor materials are grown on top of each other. This can be done using techniques such as molecular beam epitaxy or metal-organic chemical vapor deposition.
Heterostructures offer a number of benefits, including the ability to tune and control the electronic and optical properties of the material. This makes them useful for creating new devices with unique functionalities and improving the performance of existing devices.
A heterostructure is composed of layers of different materials, while a homojunction is composed of layers of the same material. This difference allows heterostructures to have more diverse electronic and optical properties compared to homojunctions.
