heterostructure
This term is used exclusively within the fields of semiconductor physics and materials science. It describes a precise engineering of materials to create a quantum well or barrier, which is the foundational technology for high-efficiency LEDs and laser diodes.
In a technical context, the term emphasizes the structural disparity between the layered materials. It is a highly formal, specialized term and is never used in casual conversation or general descriptions of mixed materials.
Meanings
Examples
The researchers developed a new heterostructure to improve electron mobility.
We need to analyze the interface of this heterostructure using a scanning tunneling microscope.
This specific heterostructure allows for the confinement of carriers in a quantum well.
I wonder if a van der Waals heterostructure could solve the lattice mismatch problem.
The device relies on a GaAs and AlGaAs heterostructure for high speed operation.
The growth of the heterostructure was achieved through molecular beam epitaxy.
Can we optimize the thickness of the layers in the heterostructure to reduce leakage current?
