Simultaneous measurement of anisotropic thermal conductivity and thermal boundary conductance of 2-dimensional materials
Mizanur Rahman, Mohammadreza Shahzadeh, Simone Pisana
The rapidly increasing number of 2-dimensional (2D) materials that have been isolated or synthesized provides an enormous opportunity to realize new device functionalities. Whereas…
Role of the electron-phonon coupling in tuning the thermal boundary conductance at metal-dielectric interfaces by inserting ultrathin metal interlayers
S. M. Oommen, S. Pisana
Varying the thermal boundary conductance at metal-dielectric interfaces is of great importance for highly integrated electronic structures such as electronic, thermoelectric and pl…
Speed limit of FePt spin dynamics on femtosecond timescales
J. Mendil, P. C. Nieves, O. Chubykalo-Fesenko +4
Magnetization manipulation is becoming an indispensable tool for both basic and applied research. Theory predicts two types of ultrafast demagnetization dynamics classified as type…
Phonon renormalisation in doped bilayer graphene
A. Das, B. Chakraborty, S. Piscanec +3
We report phonon renormalisation in bilayer graphene as a function of doping. The Raman G peak stiffens and sharpens for both electron and hole doping, as a result of the non-adiab…
Raman Fingerprint of Charged Impurities in Graphene
C. Casiraghi, S. Pisana, K. S. Novoselov +2
We report strong variations in the Raman spectra for different single-layer graphene samples obtained by micromechanical cleavage, which reveals the presence of excess charges, eve…
Electrochemically Top Gated Graphene: Monitoring Dopants by Raman Scattering
A. Das, S. Pisana, S. Piscanec +8
We demonstrate electrochemical top gating of graphene by using a solid polymer electrolyte. This allows to reach much higher electron and hole doping than standard back gating. In-…
Born-Oppenheimer Breakdown in Graphene
Simone Pisana, Michele Lazzeri, Cinzia Casiraghi +4
The Born-Oppenheimer approximation (BO) has proven effective for the accurate determination of chemical reactions, molecular dynamics and phonon frequencies in a wide range of meta…
