University Of Arkansas Orders Fifth Riber Research Machine


Compact 21, 3inch research system will allow studies of epitaxial Si/Ge/Sn/Pb heterostructures focused on band engineering via Sn incorporation and strain manipulation

French MBE company Riber has announced an order for a research MBE system in the United States.

Greg Salamo, director of Nanoscience and Engineering Institute from University of Arkansas, USA, has ordered Riber best seller Compact 21, 3inch research system.

This fifth Riber MBE system will complete the existing modutrac line. Apart from III-V nanoscale growths, this new reactor will also permit studies of epitaxial Si/Ge/Sn/Pb heterostructures focused on band engineering via Sn incorporation and strain manipulation.

Philippe Ley, CEO of Riber commented: “University of Arkansas Nanoscience and Engineering Institute is a 25-year-old Riber customer. It has always been a pleasure to work with Prof. Salamo and his team. Their high level of expertise, understanding and involvement in each discussion and at each step of the project has been really appreciated by all the Riber project team. We believe that the technological issues addressed here will enhance epitaxy processes and enable Arkansas MBE-STM facility to maintain state-of-the-art results.”

Greg Salamo said: “We are looking forward to receiving this new system. It will allow us to develop new SiGeSnPb technology not possible with current MBE systems. Through many cycles of discussion, we arrived at a method to control the temperature of growth at low temperatures of 100°C to 300°C, which will be tested with emphasis on our requested specs. As in the past, when we work with Riber to integrate STM, Riber scientists were amazing helpful, including modeling different designs, and we look forward to this and further collaborations with Riber.”

This order will be delivered in 2022.
