Mikhail Iosifovich Katsnelson (Russian: Михаил Иосифович Кацнельсон; born 10 August 1957) is a Russian-Dutch professor of theoretical physics.

In 1985 he defended his thesis for his Doctor of Science degree called Strong electron correlations in transition metals, their alloys and compounds and from 1990 to 1998 became Max-Planck-Institute visiting professor.

[3] From 2004 to 2007 Katsnelson worked with many Russian and Dutch physicists on the nitrogen dioxide and discovered that its closed shell dimer N2O4 creates only weak doping which is also known as density of states in a graphene.

[5] In 2010 Katsnelson worked with physicists from India such as Rashid Jalil, Rahul R. Nair, and nanotechnologist Fredrik Schedin of University of Manchester and have discovered that fluorine atoms are attached to the carbon of the graphene, therefore creating a new version called fluorographene that can be stable in the air with a temperature of 400 °C (752 °F).

[6] In 2012 he and his colleagues have used prototype device which contained graphene heterojunctions which was combined with either thin boron nitride or molybdenum disulfide which was used as a vertical transport barrier.
