Interfacial Chemistry Triggers Ultrafast Radiative Recombination in Metal Halide Perovskites

Autor: Haiyun Dong, Chunhuan Zhang, Weijie Nie, Shengkai Duan, Christian N. Saggau, Min Tang, Minshen Zhu, Yong Sheng Zhao, Libo Ma, Oliver G. Schmidt

Publikováno v: Angewandte Chemie International Edition. 61

Efficient radiative recombination is essential for perovskite luminescence, but the intrinsic radiative recombination rate as a basic material property is challenging to tailor. Here we report an interfacial chemistry strategy to dramatically increas

Maximally entangled and gigahertz-clocked on-demand photon pair source

Autor: Weijie Nie, C. Hopfmann, Fei Ding, Oliver G. Schmidt, Carmen Weigelt, Nand Lal Sharma

Publikováno v: Physical Review B

We present a 1 GHz-clocked, maximally entangled and on-demand photon pair source based on droplet etched GaAs quantum dots using two-photon excitation. By employing these GaP microlensenhanced devices in conjunction with their substantial brightness,

Photoneutralization of charges in GaAs quantum dot based entangled photon emitters

Autor: Jingzhong Yang, Tom Fandrich, Frederik Benthin, Robert Keil, Nand Lal Sharma, Weijie Nie, Caspar Hopfmann, Oliver G. Schmidt, Michael Zopf, Fei Ding

Publikováno v: Physical Review B 105 (2022), Nr. 11

Semiconductor-based emitters of pairwise photonic entanglement are a promising constituent of photonic quantum technologies. They are known for the ability to generate discrete photonic states on-demand with low multiphoton emission, near-unity entan

Heralded preparation of spin qubits in droplet-etched GaAs quantum dots using quasiresonant excitation

Autor: Weijie Nie, C. Hopfmann, Oliver G. Schmidt, Fei Ding, Nand Lal Sharma, Robert Keil

We present a comprehensive study on heralded spin preparation employing excited state resonances of droplet-etched GaAs quantum dots. This achievement will facilitate future investigations of spin qubit based quantum memories using the GaAs quantum d
