Optimized nanodevice fabrication using clean transfer of graphene by polymer mixture: Experiments and Neural Network based simulations

Autor: Averitt, Jared K., Pourianejad, Sajedeh, Ayodele, Olubunmi, Schmidt, Kirby, Trofe, Anthony, Starobin, Joseph, Ignatova, Tetyana

In this study, we investigate both experimentally and computationally the molecular interactions of two distinct polymers with graphene. Our experimental findings indicate that the use of a polymer mixture reduces the transfer induced doping and stra

Multimodal Image Registration of Raman Spectral Maps in Two Dimensional Materials by Strain and Doping Analysis

Autor: Schmidt, Kirby, Trofe, Anthony, Ignatova, Tetyana

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 dimensional materials is particularly difficult due to the lack of keypoi

Multidimensional imaging reveals mechanisms controlling label-free biosensing in vertical 2DM-heterostructures

Autor: Ignatova, Tetyana, Pourianejad, Sajedeh, Li, Xinyi, Schmidt, Kirby, Aryeetey, Frederick, Aravamudhan, Shyam, Rotkin, Slava V.

Two-dimensional materials and their van der Waals heterostructures enable a large range of applications, including label-free biosensing. Lattice mismatch and work function difference in the heterostructure material result in strain and charge transf

Two-color spectroscopy of UV excited ssDNA complex with a single-wall nanotube probe: Fast nucleobase autoionization mechanism

Autor: Ignatova, Tetyana, Balaeff, Alexander, Zheng, Ming, Blades, Michael, Stoeckl, Peter, Rotkin, Slava V.

Publikováno v: Nano Research 9, 571-583 (2015)

DNA autoionization is a fundamental process wherein UV-photoexcited nucleobases dissipate energy by charge transfer to the environment without undergoing chemical damage. Here, single-wall carbon nanotubes (SWNT) are explored as a photoluminescent re
