Nanostructures are classified based on the number of dimensions confined to the nanorange (typically 1-100 nm). A Quantum well is a structure where carriers (like electrons or holes) are confined in one dimension (e.g., a very thin layer or film), while being free to move in the other two dimensions.
If in a material one dimension is reduced to the Nano range while the other two dimensions remain large, the structure so obtained is known as
