Graphene nanopipette enabled liquid delivery at zeptoliter precision
Shi Qiu, Yu Chen, Gediminas Gervinskas +4
Accurate extraction of liquid is the first step towards low-volume liquid delivery and nanocharacterization, which plays a significant role in biomedical research. In this study, a…
Direct imaging of liquid-nanoparticle interface with atom probe tomography
Shi. Qiu, Changxi Zheng, Qi Zhou +8
Understanding the structure and chemical composition at the liquid-nanoparticle (NP) interface is crucial for a wide range of physical, chemical and biological processes. In this s…
Multidimensional Analysis of Excitonic Spectra of Monolayers of Tungsten Disulphide: Towards Computer Aided Identification of Structural and Environmental Perturbations of 2D Materials
Pavel V. Kolesnichenko, Qianhui Zhang, Changxi Zheng +2
Despite 2D materials holding great promise for a broad range of applications, the proliferation of devices and their fulfillment of real-life demands are still far from being reali…
Electronic bandstructure of in-plane ferroelectric van der Waals
James L. Collins, Chutian Wang, Anton Tadich +11
Layered indium selenides () have recently been discovered to host robust out-of-plane and in-plane ferroelectricity in the and ' phases, respectively. In this…
Disentangling the effects of doping, strain and defects in monolayer WS2 by optical spectroscopy
Pavel V. Kolesnichenko, Qianhui Zhang, Changxi Zheng +2
Monolayers of transition metal dichalcogenides (TMdC) are promising candidates for realization of a new generation of optoelectronic devices. The optical properties of these two-di…
Helicity resolved Raman scattering of MoS2, MoSe2, WS2 and WSe2 atomic layers
Shao-Yu Chen, Changxi Zheng, Michael S. Fuhrer +1
The two-fold valley degeneracy in two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDCs) (Mo,W)(S,Se)2 is suitable for "valleytronics", the storage and manupu…
