Mg substrates are ideal for research in nanotechnology and nanomaterials. Their well-defined crystal structure supports the growth of nanostructures like nanowires, nanotubes, and quantum dots. The high surface quality and crystalline orientation of Mg wafers make them an excellent choice for studies focused on nanoscale phenomena and material behavior. This is crucial in the development of new nanoscale devices and materials.

4. Thermal Management Systems

Thanks to their high thermal conductivity, Mg substrates are employed in thermal management applications, particularly in electronic devices that require efficient heat dissipation. Mg substrates can be used as the base for heat sinks in electronics such as CPUs and power transistors. This helps to prevent overheating and improves the efficiency and lifespan of the device by maintaining optimal operating temperatures.

5. Biodegradable Biomedical Implants

Mg substrates are gaining attention in the biomedical field due to magnesium’s biocompatibility and biodegradability. Research into biodegradable implants uses Mg substrates to test the material’s behavior in biological environments. Magnesium-based implants are designed to gradually degrade and be absorbed by the body, reducing the need for surgical removal. This has potential applications in bone fixation devices and other temporary medical implants.
