STM driven transition from rippled to buckled graphene in a spin-membrane model
Miguel Ruiz-Garcia, Luis L. Bonilla, Antonio Prados
We consider a simple spin-membrane model for rippling in graphene. The model exhibits transitions from a flat but rippled membrane to a buckled one. At high temperature the transit…
Enhancing Chaotic Behavior at room temperature in GaAs/(Al,Ga)As Superlattices
Miguel Ruiz-Garcia, Jonathan Essen, Manuel Carretero +2
Previous theoretical and experimental work has put forward 50-period semiconductor superlattices as fast, true random number generators at room temperature. Their randomness stems…
Critical radius and temperature for buckling in graphene
L. L. Bonilla, M. Ruiz-Garcia
In this work, we find an analytical flat-membrane solution to the saddle point equations, derived by Guinea et al. [Phys. Rev. B 89, 125428 (2014)], for the case of a suspended gra…
