Ultra-Confinement of Polaritons in Single Atomic Layer Ag Photonic Quantum Dots
Xinyi Li, Tetyana Ignatova, Chengye Dong +8
Light scattering by two-dimensional (2D) van der Waals heterostructures (vdWHs) is immense, especially given their infinitesimal volume, thus enabling strong light-matter interacti…
Optimized nanodevice fabrication using clean transfer of graphene by polymer mixture: Experiments and Neural Network based simulations
Jared K. Averitt, Sajedeh Pourianejad, Olubunmi Ayodele +4
In this study, we investigate both experimentally and computationally the molecular interactions of two distinct polymers with graphene. Our experimental findings indicate that the…
Multimodal Image Registration of Raman Spectral Maps in Two Dimensional Materials by Strain and Doping Analysis
Kirby Schmidt, Anthony Trofe, Tetyana Ignatova
It is common to measure a single sample using multiple different microscopy methods that have variable scales, rotation and translation. Registering hyperspectral images of two dim…
Multidimensional imaging reveals mechanisms controlling label-free biosensing in vertical 2DM-heterostructures
Tetyana Ignatova, Sajedeh Pourianejad, Xinyi Li +4
Two-dimensional materials and their van der Waals heterostructures enable a large range of applications, including label-free biosensing. Lattice mismatch and work function differe…
Two-color spectroscopy of UV excited ssDNA complex with a single-wall nanotube probe: Fast nucleobase autoionization mechanism
Tetyana Ignatova, Alexander Balaeff, Ming Zheng +3
DNA autoionization is a fundamental process wherein UV-photoexcited nucleobases dissipate energy by charge transfer to the environment without undergoing chemical damage. Here, sin…
