History of the conferences

EP2DS (International Conference on Electronic Properties of Two-Dimensional Systems) made its debut during August 24-28, 1975, at Brown University in Providence, Rhode Island, USA. In those early days, the scope of the conference at first was concerned primarily with artificial two-dimensional systems, such as electrons on surfaces, at interfaces, or confined within layered materials. With the expansion of participants’ interests into yet lower dimensions, the conference has for many years also covered one- and even zero- dimensional systems.

MSS (International Conference on Modulated Semiconductor Structures) began life as “Metastable and Modulated Semiconductor Structures (MMSS)” held December 6-10, 1982, in Pasadena, California, USA.

The conference adopted its present name in 1985 and, since then, it has been regularly organized every 2 years. The purpose of MSS is to provide an international forum on the latest progress in the field of physics, formation, processing, and device applications of modulated structures.

The two conferences were first jointly held in 1985, combining EP2DS-6 and MSS-2 in Kyoto, Japan. Tsuneya Ando (Chair of EP2DS) and Hiroyuki Sakaki (Chair of MSS) decided to hold the two conferences in parallel at the same location, enabling the participants to freely come and go between the two. Building on the success of this joint conference, they were again held together in Nara, Japan, in 1991, and again in Nara in 2003; and since then they have been jointly held every two years (excepting some disruption during the pandemic).

The two series of conferences have served as the stages for finding and exploring important novel concepts in physics and technologies such as superlattices, the Wigner lattice, the quantum Hall effects, quantum wires and dots, spintronics, the BECs of complex particles, graphene physics and devices, and topological phases. Since the mid-2000s, the definition of two-dimensional system has expanded greatly to include the large family of atomically thin materials.

The joint conference series is now established as a major event in the research fields of modulated semiconductors and low-dimensional electron systems. The most recent versions of the conference were in Grenoble, France, in 2023; as a virtual conference based in Toyama, Japan in 2021; and at Penn State University in 2017.
