Breaking inversion symmetry in materials allows deviations from Ohm's law, enabling nonlinear effects that could drive future nano- and quantum-electronic devices. (Nanowerk News) The Nanodevices ...
The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...
The Nanodevices group at CIC nanoGUNE shows that breaking a material’s inversion symmetry can shatter Ohm’s law, unleashing powerful nonlinear phenomena. Their review, just published in Nature ...
