Impact Ionization and Carrier Multiplication in Graphene
L. Pirro, A. Girdhar, Y. Leblebici +1
We develop a model for carrier generation by impact ionization in graphene, which shows that this effect is non-negligible because of the vanishing energy gap, even for carrier tra…

Soft Carrier Multiplications by Hot Electrons in Graphene
Anuj Girdhar, Jean-Pierre Leburton
By using Boltzmann formalism, we show that carrier multiplication by impact ionization can take place at relatively low electric fields during electronic transport in graphene. Bec…
