Sub-wavelength optical lattice in 2D materials

Autor: Sarkar, Supratik, Mehrabad, Mahmoud Jalali, Suárez-Forero, Daniel G., Gu, Liuxin, Flower, Christopher J., Xu, Lida, Watanabe, Kenji, Taniguchi, Takashi, Park, Suji, Jang, Houk, Zhou, You, Hafezi, Mohammad

Recently, light-matter interaction has been vastly expanded as a control tool for inducing and enhancing many emergent non-equilibrium phenomena. However, conventional schemes for exploring such light-induced phenomena rely on uniform and diffraction

Electrical control and transport of tightly bound interlayer excitons in a MoSe2/hBN/MoSe2 heterostructure

Autor: Zhang, Lifu, Ni, Ruihao, Gu, Liuxin, Xie, Ming, Park, Suji, Jang, Houk, Taniguchi, Takashi, Watanabe, Kenji, Zhou, You

Controlling interlayer excitons in van der Waals heterostructures holds promise for exploring Bose-Einstein condensates and developing novel optoelectronic applications, such as excitonic integrated circuits. Despite intensive studies, several key fu

Chiral Flat-Band Optical Cavity with Atomically Thin Mirrors

Autor: Suárez-Forero, Daniel G., Ni, Ruihao, Sarkar, Supratik, Mehrabad, Mahmoud Jalali, Mechtel, Erik, Simonyan, Valery, Grankin, Andrey, Watanabe, Kenji, Taniguchi, Takashi, Park, Suji, Jang, Houk, Hafezi, Mohammad, Zhou, You

A fundamental requirement for photonic technologies is the ability to control the confinement and propagation of light. Widely utilized platforms include two-dimensional (2D) optical microcavities in which electromagnetic waves are confined between e

Giant optical nonlinearity of Fermi polarons in atomically thin semiconductors

Autor: Gu, Liuxin, Zhang, Lifu, Ni, Ruihao, Xie, Ming, Wild, Dominik S., Park, Suji, Jang, Houk, Taniguchi, Takashi, Watanabe, Kenji, Hafezi, Mohammad, Zhou, You

Realizing strong nonlinear optical responses is a long-standing goal of both fundamental and technological importance. Recently significant efforts have focused on exploring excitons in solids as a pathway to achieving nonlinearities even down to few

Excitation-Dependent High-Lying Excitonic Exchange via Interlayer Energy Transfer from Lower-to-Higher Bandgap 2D Material

Autor: Karmakar, Arka, Kazimierczuk, Tomasz, Antoniazzi, Igor, Raczyński, Mateusz, Park, Suji, Jang, Houk, Taniguchi, Takashi, Watanabe, Kenji, Babiński, Adam, Al-Mahboob, Abdullah, Molas, Maciej R.

High light absorption (~15%) and strong photoluminescence (PL) emission in monolayer (1L) transition metal dichalcogenide (TMD) make it an ideal candidate for optoelectronic applications. Competing interlayer charge (CT) and energy transfer (ET) proc
