DESCRIPTION:Prof. Andras Kis\, Institute of Electricity and Institute of M
 aterials Science\, EPFL\nINAUGURAL LECTURE\nAbstract:\nSemiconductors are 
 an essential class of materials being behind many of the technological adv
 ances that marked the development of electronics and the related semicondu
 ctor industry. The development of new semiconducting materials could be on
 e solution to a problem plaguing the semiconductor industry today: that of
  rising heat dissipation in transistors in microchips\, which led to compu
 ter speeds increasing at a much slower pace today than 10-15 years ago.\nT
 he so-called two-dimensional materials could be especially interesting in 
 this context. They consist of single planes extracted from crystals of lay
 ered materials. Since the thickness of these planes is smaller than 1 nm a
 nd is usually on the scale of 1-3 atoms\, two-dimensional materials repres
 ent the ultimate limit of miniaturization in the vertical dimension.\nThe 
 first two-dimensional material under intense study was graphene\, a single
  layer of graphite\, made popular by a series of breakthroughs in 2004 and
  2005. In spite of initial optimism\, researchers are still looking for pr
 actical applications of this material\, especially in the context of elect
 ronics where the lack of a band gap\, a defining feature of semiconductors
 \, made graphene much less interesting than initially thought. In 2010 my 
 group made a breakthrough in this field by using a single layer of molybde
 num disulphide (MoS2)\, a true 2D semiconductor\, to realize the first tra
 nsistor based on semiconducting single layers. This opened the way to expl
 oring the science and application of a broad range of 2D semiconducting ma
 terials which were initially overlooked. Some of these materials and their
  uses in integrate circuits\, memory elements\, photodetectors and light e
 mitting devices will be presented.\nProgram:\n- Introduction by Prof. Deme

 gree in physics from the University of Zagreb in 1999. He joined the group
  of Prof. László Forró at EPFL where he earned his PhD in 2003 for whic
 h he was awarded the Latsis prize in 2004. Between 2004 and 2007\, he was 
 working as a postdoctoral researcher at the University of California\, Ber
 keley\, in the group of Prof. Alex Zettl. In 2008 he joined EPFL as an Ass
 istant Professor of Electrical Engineering and was promoted to an associat
 e Professor in 2015. He is a recipient of two ERC grants:  a Starting gra
 nt in 2009 and a Consolidator grant in 2015. His group is interested in fu
 ndamental properties and practical applications of 2D materials.
