摘要

我们研究了光载流子掺杂对单层WSe2中高次谐波产生的影响。光载流子掺杂引起的谐波强度变化表明，在低能量区，带间机制和带内机制与吸收边相似，而在高能量区，带间机制占主导地位。

Photo-carrier doping effect on high-order harmonic generation in monolayer WSe2

We have investigated the photo-carrier doping effect on high-order harmonic generation in monolayer WSe2. The intensity change of harmonics induced by the photo-carrier doping suggests that the interband and intraband mechanism is comparable in the lower energy region than the absorption edge whereas the interband mechanism is dominant in the higher energy region.
