In this article, we explore the role of a Research Scientist at VTT, the importance of MOVPE in epitaxial growth, and the groundbreaking impact this position will have on future semiconductor devices and technologies.

What is Epitaxial Growth of III-Nitrides?

Epitaxy is a process used to grow single-crystal thin films on a substrate, essential for fabricating high-quality semiconductors. The epitaxial growth of III-nitride semiconductors, such as Gallium Nitride (GaN) and Aluminum Gallium Nitride (AlGaN), has gained significant attention for its remarkable performance in electronic devices. These materials have unique properties, including wide bandgaps, high electron mobility, and resistance to high power densities, making them ideal for applications in power electronics, optoelectronics, and high-frequency devices.

The epitaxial growth process using MOVPE is particularly advantageous for fabricating III-N thin films, allowing precise control over material composition, film thickness, and doping levels. MOVPE is recognized for its ability to produce high-quality, large-area epitaxial films suitable for industrial applications in energy-efficient power transistors, LEDs, and other high-performance electronic components.
