Layered two-dimensional (2D) materials MoTe2 have been paid special attention due to the rich optoelectronic properties with various phases. The nonequilibrium carrier dynamics as well as its temperature dependence in MoTe2 are of prime importance, as it can shed light on understanding the anomalous optical response and potential applications in far infrared (IR) photodetection. Hereby, we employ timeresolved terahertz (THz) spectroscopy to study the temperature dependent nonequilibrium carrier… Expand

Exact solution of two simple non-equilibrium electron-phonon and electron-electron coupled systems: The atomic limit of the Holstein-Hubbard model and the generalized Hatsugai-Komoto model
One of the challenges in many-body physics is determining the effects of phonons on strongly correlated electrons. The difficulty arises from strong correlations at differing energy scales—for bandExpand


Anisotropic Broadband Photoresponse of Layered Type-II Weyl Semimetal MoTe2.
The results suggest this emerging class of materials can be harnessed for broadband angle sensitive, self-powered photodetection with decent responsivities, and the response of the detector is polarization angle sensitive due to the anisotropic response of MoTe2. Expand

Observation of a transient decrease in terahertz conductivity of single-layer graphene induced by ultrafast optical excitation.
The terahertz frequency-dependent sheet conductivity and its transient response following femtosecond optical excitation for single-layer graphene samples grown by chemical vapor deposition shows that the negative photoconductive response arises from an increase in the carrier scattering rate, with a minor offsetting increase inThe Drude weight.
