摘要

我们报道了在10-250 meV光子的脉冲激发下外延生长石墨烯中接近狄拉克点的载流子弛豫动力学。随着光子能量的降低，我们确定了不同的机制-诱导传输与双指数和单指数衰减以及诱导吸收-并讨论了它们的物理起源。

Nonlinear transmission dynamics in graphene close to the Dirac point

We report on carrier relaxation dynamics close to the Dirac point in epitaxially grown graphene under pulsed excitation with 10–250 meV photons. With decreasing photon energy, we identify different regimes — induced transmission with bi- and single-exponential decay as well as induced absorption — and discuss their physical origin.
