Etymology
Heterostructure begins with hetero- meaning 'different' and ends with the familiar word structure meaning a 'built thing' or 'arrangement'. So a heterostructure is a structure made by joining layers of different materials, which helps explain why it is used to control electron flow in electronic devices.
