Vivek Kumar Singh,Anuj Shukla,Manoj Kumar Patra,Lokesh Saini,Raj Kumar Jani,Sampat Raj Vadera,Narendra Kumar +6 more
TL;DR: In this paper, reduced graphene oxide (RGO) with a layered and porous structure was synthesized by thermal exfoliation of graphite oxide using Fourier transform infrared and Raman spectroscopies, X-ray diffraction and scanning electron microscopy.
Journal ArticleDOI
In situ synthesis of graphene oxide and its composites with iron oxide
Vivek Kumar Singh,Manoj Kumar Patra,M. Manoth,Genekehal Siddaramana Gowd,Sampat Raj Vadera,N. Kumar +5 more
TL;DR: In this paper, a single step method was developed for the preparation of graphene oxide/Fe2O3 composites by exfoliation of graphite oxide with an oxygen-rich ferric acetyl acetonate complex.
Journal ArticleDOI
Molecular n-doping of chemical vapor deposition grown graphene
Arun Kumar Singh,M. W. Iqbal,Vivek Kumar Singh,Muhammad Zahir Iqbal,Jae Hong Lee,Seung-Hyun Chun,Koo Shin,Jonghwa Eom +7 more
TL;DR: In this article, the modification of the electronic properties of single layer CVD-grown graphene by molecular doping without degrading its transparency and electrical properties was reported, where the shift of G and 2D peak wave numbers and the intensity ratio of D and G peaks were analyzed as a function of reaction time.
Journal ArticleDOI
Tailoring the electrical properties of graphene layers by molecular doping.
TL;DR: This study demonstrates that chemical modification is a simple approach to tailor the electrical properties of single-, bi-, and trilayer graphenes, while maintaining the important electrical assets.
