Enhanced trion emission in monolayer MoSe2 by constructing a type-I van der Waals heterostructure

Juanmei Duan, Phanish Chava, Mahdi Ghorbani-Asl +10

Trions, quasi-particles consisting of two electrons combined with one hole or of two holes with one electron, have recently been observed in transition metal dichalcogenides (TMDCs…

Optical Kerr nonlinearity and multi-photon absorption of DSTMS measured by Z-scan method

Jiang Li, Rakesh Rana, Liguo Zhu +3

We investigate the optical Kerr nonlinearity and multi-photon absorption (MPA) properties of DSTMS excited by femtosecond pulses at a wavelengths of 1.43 μm, which is optimal for t…

Silicon-based Intermediate-band Infrared Photodetector realized by Te Hyperdoping

Mao Wang, Eric García-Hemme, Yonder Berencén +7

Si-based photodetectors satisfy the criteria of low-cost and environmental-friendly, and can enable the development of on-chip complementary metal-oxide-semiconductor (CMOS)-compat…

Photoluminescence dynamics in few-layer InSe

Tommaso Venanzi, Himani Arora, Stephan Winnerl +10

We study the optical properties of thin flakes of InSe encapsulated in hBN. More specifically, we investigate the photoluminescence (PL) emission and its dependence on sample thick…

Mode-locked ultrashort pulses from an 8 m wavelength semiconductor laser

Johannes Hillbrand, Nikola Opacak, Marco Piccardo +4

Quantum cascade lasers (QCL) have revolutionized the generation of mid-infrared light. Yet, the ultrafast carrier transport in mid-infrared QCLs has so far constituted a seemingly…
