Our Founder's Message


Stefan Birner



I am Stefan Birner, the founder and managing director of nextnano GmbH.

The nextnano software originated from an idea around the year 2000 at the Walter Schottky Institute of the Technische Universität München, aiming to develop a highly versatile software for the three-dimensional modeling of quantum effects in semiconductor heterostructures. The software was developed within the Theoretical Semiconductor Physics group led by Professor Peter Vogl.

Motivated by our successful participation in the Munich Business Plan Competition, as well as the entrepreneurial education I received during my PhD studies at UnternehmerTUM, I decided to establish a company to commercialize this software. Upon completing my PhD and with the retirement of my professor, I realized this idea in 2012.

nextnano has evolved through the collective feedback from hundreds of passionate users seeking to understand the physics within their semiconductor nanostructures. I was overwhelmed by the positive feedback from our users.

Since 2012, we have continuously supported researchers at universities, government research institutions, and companies of all sizes worldwide. We are committed to empowering both PhD students and learning professionals to achieve more with our software. Join us on this journey of studying quantum effects in semiconductor nanodevices.

Our Logo


nextnano logo



Our logo represents the quantum state n in the ket notation which is used by physicists to describe quantum mechanics in mathematical language (a complex vector in Linear Algebra). nextnano has been derived from the idea to develop a “next generation 3D nanodevice simulator” (nextnano³), a simulator for modeling the next generation of tiny semiconductor devices exploiting quantum effects.
