Tuning the surface termination of InP offers a delicate yet effective way to selectively stabilize MnTe polymorphs during epitaxial growth, creating opportunities to realize emergent quantum behaviors such as altermagnetism (left) and novel dielectric functionalities (right).

Scientific Achievement: Molecular beam epitaxy and first principles calculations demonstrate that substrate termination can be used to control the crystal phase and functional properties.
Significance and Impact: Epitaxy provides a powerful “design knob” for stabilizing targeted quantum states through interfacial phase engineering, thereby enabling new technologies such as altermagnetic spintronics and multifunctional electronics.
