On December 6, 2019, the in-situ closed-loop low-temperature transport system provided by Fermion Instruments to Professor Zhang Yuanbo of Fudan University completed on-site installation and testing. The system can achieve ultra-high vacuum interconnection of MBE growth and in-situ 10-electrode transport measurement, and the minimum sample temperature is less than 4K. All indicators meet the contract standards.

Dr. Ou Hongwei, General Manager of Fermion Instruments, and Professor Zhang Yuanbo attended the acceptance ceremony. At the same time, Dr. Ou Hongwei presented Professor Zhang Yuanbo with a commemorative trophy to thank Professor Zhang for his long-term support and encouragement for domestic scientific research equipment.

Professor Zhang Yuanbo has long been committed to the exploration of two-dimensional materials and has developed a variety of sample preparation and detection methods to study the structure and electromagnetic properties of low-dimensional materials and to find possible new quantum ground states. Through innovative experimental means and methods, a series of representative achievements have been made, including the first successful preparation of field effect transistor devices based on new two-dimensional crystal black phosphorus in the world; the discovery of a new type of magnetic two-dimensional material Fe3GeTe2, which provides a new ideal system for studying two-dimensional itinerant magnetism, etc. In order to meet the experimental needs, Professor Zhang Yuanbo has successively ordered three non-standard systems from Fe-Mian Instruments for MBE growth, two-dimensional material preparation, and low-temperature transport testing, so as to better study the structure and physical properties of low-dimensional systems. These three systems are all aimed at Professor Zhang's special experimental needs, making full use of existing standardized modules, and are achieved through the upgrade and reasonable matching of standardized modules. This fully demonstrates the technical strength of Fe-Mian Instruments in the fields of ultra-high vacuum interconnection, thin film growth, and ultra-low temperature, and also proves the feasibility of the idea of "standardized modules, non-standardized systems" promoted by Fe-Mian Instruments, which can meet the ever-changing and improved instrument needs of scientific researchers.

Fermion Instruments has established good long-term cooperative relations with many top research groups and national laboratories in China, and at the same time implemented the needs into design and physical objects, helping domestic scientific research. We also hope to work with more outstanding scientific workers in China to innovate and create a better future through the cooperation of science and engineering.
