Noise and charge discreteness as ultimate limit for the THz operation of ultra-small electronic devices
Enrique Colomés, Javier Mateos, Tomás González +1
To manufacture faster electron devices, the industry has entered into the nanoscale dimensions and Terahertz (THz) working frequencies. The discrete nature of the few electrons pre…
Antichiral edge states in a modified Haldane nanoribbon
E. Colomés, M. Franz
Topological phases of fermions in two-dimensions are often characterized by chiral edge states. By definition these propagate in the opposite directions at the two parallel edges w…
Limitations of the intrinsic cut-off frequency to correctly quantify the speed of nanoscale transistors
Zhen Zhan, Enrique Colomés, Xavier Oriols
The definition of the intrinsic cut-off frequency () based on the current gain equals to one (0 dB) is critically analyzed. A condition for the validity of the quasi-static es…
Time-dependent simulation of particle and displacement currents in THz graphene transistors
Z. Zhan, E. Colomès, A. Benali +2
Although time-independent models provide very useful dynamical information with a reduced computational burden, going beyond the quasi-static approximation provides enriched inform…
