Recently, the CD laboratory at the University of Graz (TU Graz) has made important progress in the exploration of new semiconductor materials. This research project aims to discover and develop semiconductor materials that will drive the performance, efficiency, and sustainability of next-generation electronic devices in response to the growing demands of modern electronics.
With the rapid development of artificial intelligence, 5G, autonomous driving and other technologies, the requirements for semiconductor materials are getting higher and higher. Existing silicon-based materials have already reached bottlenecks in terms of speed, energy efficiency, and miniaturization, making it difficult to meet the development needs of future technologies. Therefore, exploring new semiconductor materials and breaking the limitations of silicon-based materials has become one of the key directions of global semiconductor research.
TU Graz's CD Lab is focused on discovering and optimizing semiconductor materials that can replace or enhance silicon-based technologies. Through interdisciplinary collaborations, the lab is working on many different types of materials, including compound semiconductors, organic semiconductors, two-dimensional materials such as graphene and transition metal dichalcogenides, and more. These new materials have unique electrical, optical, and thermal properties that enable them to deliver higher performance than traditional silicon materials, especially in key areas such as power efficiency, speed, and integration density.
One of the main research directions of the laboratory is the development of materials that can operate at higher operating frequencies and process more data with lower energy consumption. Especially in the field of high-speed data transmission such as 5G, new semiconductor materials can meet the demand for high-speed data transmission without generating excessive heat. In addition, with the growing global focus on sustainability, research is also focusing on materials that not only have excellent performance, but are also more environmentally friendly, and have a lower environmental impact on production and recycling processes.

Another exciting area of research is how new materials can improve the scalability of semiconductor devices. As semiconductor technology continues to shrink, there is a growing need for materials that can maintain excellent performance in smaller sizes. The new materials developed by CD Labs are expected to maintain the excellent electrical properties of integrated circuits as they continue to be miniaturized, supporting the continuation of Moore's Law, which is that the number of transistors on a chip doubles every two years or so. This research is critical to ensuring that the next generation of electronic devices can continue to become smaller, more powerful, and more efficient.
The research at the University of Graz is not limited to the theoretical level of materials research, but also works closely with industry to ensure that the research results meet the practical needs of the semiconductor industry. Through cooperation with semiconductor manufacturers, the laboratory translates its research results into concrete technological innovations that not only advance the academic field, but also promote practical applications and advance the industry.
With the wide application of semiconductor technology in many fields such as medical, automotive, consumer electronics, etc., the research work of the University of Graz will have a profound impact. Breakthroughs in new materials will make electronics more efficient and powerful, while also paving the way for innovation in quantum computing, energy storage, advanced communication systems, and more.
In general, the work of the CD Laboratory at the University of Graz in the field of semiconductor materials research has given a new impetus to the development of the semiconductor industry. By pushing the boundaries of materials science, researchers are solving the major challenges facing the semiconductor industry in terms of performance, efficiency, and sustainability. With the increasing demand for speed, volume and energy efficiency in electronic devices, these innovations from the laboratory will undoubtedly play an important role in the development of the global digital economy.
