Michel Houssa earned his master's and PhD in physics at the University of Liege, Belgium. He is presently a professor in the Department of Physics and Astronomy at the University of Leuven, Belgium. His current research focuses on the first principles modeling of various materials, including semiconductor/oxide interfaces and two-dimensional materials (silicene, germanene, and transition metal dichalcogenides), and their heterostructures. He has authored or co-authored nearly 350 publications, given about 50 invited talks and seminars, and been co-organiser of several international symposia and conferences. He is an Electrochemical Society fellow and an Institute of Electrical and Electronics Engineers senior member. Athanasios Dimoulas earned his PhD in applied physics at the University of Crete, Greece. He is currently the research director and head of the Epitaxy and Surface Science Laboratory at the National Center for Scientific Research Demokritos, Athens, Greece. He has coordinated several European-funded projects in advanced CMOS and received the European Research Council-funded SMARTGATE - Smart Gates for the 'Green' Transistor Advanced Investigator Grant 2011 - IDEAS. Widely published, Dr. Dimoulas has about 40 invited talks and has been active with several symposia, conferences, and committees as an organizer and chair. He has held fellowships at the University of Groningen, Holland; California Institute of Technology, Pasadena, USA; and University of Maryland, College Park, USA; and been a visiting research scientist at IBM Zurich Research Laboratory, Switzerland. Alessandro Molle earned his PhD in materials science at the University of Genoa, Italy. He is presently a research scientist and group leader of the research line on low-dimensional materials and devices in the MDM Laboratory at the Consiglio Nazionale delle Ricerche-Istituto per la Microelettronica e Microsistemi (CNR-IMM), Agrate Brianza, Italy. He is currently involved in the integration of silicene and other 2D elementary materials into transistors, and in the synthesis and structural characterisation of 2D materials beyond graphene. Widely published, he has been active with symposia, received many invitations to present at international conferences, and guest edited special issues of proceeding papers. He has been co-chairing a master's course on surfaces and interfaces at the University of Milano-Bicocca, Italy.
