Large area chemical vapor deposited graphene and hexagonal boron nitride was used to fabricate graphene – hexagonal boron nitride – graphene symmetric field effect transistors. Gate control of the tunneling characteristics is observed similar to previously reported results for exfoliated graphene – hexagonal boron nitride – graphene devices. Density-of-states features are observed in the tunnel...
In this paper, we used green's function approach in microscopic theory to investigate a resonant tunneling diode (RTD). We introduced the detailed Hamiltonian for each part of the photovoltaic p-i-n system, then by calculating the green's function components in tight-binding approximation, we calculate local density of states and current-voltage characteristic of the p-i-n structure. Our result...

This experimental thesis deals with self-organization phenomena in electrochemical systems. Two aspects are considered. On the one hand, the impact of a periodic variation of the applied voltage on a bistable electrochemical system is investigated. On the other hand, the interaction of an oscillatory reaction kinetics with a spatial coupling via the electric field of the electrolyte (migration ...
We used whole genome microarray analysis to identify potential candidate genes with differential expression in BRAFV600E vs NRASQ61R melanoma cells. We selected, for comparison, a peculiar model based on melanoma clones, isolated from a single tumor characterized by mutually exclusive expression of BRAFV600E and NRASQ61R in different cells. This effort led us to identify two genes, SEMA6A and M...
