Abstract

We demonstrate the first “nonlocal” nanoscale NIR-pump THz-probe measurements of semi-insulating GaAs using a scattering-type scanning near-field microscopy technique. We observe temporal shifts in the photoexcitation response which correspond to lateral offsets in the pump spot.

近场非局部光泵浦-太赫兹探测器

我们利用散射型扫描近场显微镜技术首次展示了半绝缘GaAs的“非局部”纳米级nir泵浦太赫兹探针测量。我们观察到光激发响应的时间位移，对应于泵点的横向偏移。
