Epitaxy of single-crystalline semiconductors lay the foundations for advanced electronics and optoelectronics by providing the active materials for devices. To achieve the highest device performance, single-crystalline films with minimal dislocation density are desired. Conventional approaches have limitations because of lattice mismatch and thermal expansion mismatch. Accordingly, several advanced approaches have been developed, such as low-temperature buffer approach, lattice-engineered buffer approach, metamorphic buffer approach, epitaxial lateral overgrowth, domain-matched epitaxy, van der Waals epitaxy, and remote epitaxy.
To achieve complex heterostructures with large lattice mismatch, researchers have developed alternative approaches such as lift-transfer and layer transfer, which give the freedom to transfer epitaxial materials onto target substrates. In this Special Topic, we address current progress and challenges in advanced epitaxy.
Topics covered include, but are not limited to:
- Van der Waals epitaxy
- Remote epitaxy
- Lattice mismatch management
- Thermal expansion mismatch management
- Structural configuration
- Lift-off and layer-transfer method
- III-V on Si
- Advanced modeling and characterization
- High performance devices
