Detection of polar chemical vapors using epitaxial graphene grown on SiC (0001)

(author unknown)



V. K. Nagareddy, H. K. Chan, and S. C. Hernández et al.

Epitaxial graphene grown on SiC (0001) showed significant changes in electrical resistance upon exposure to polar protic and polar aprotic vapors in the ambient atmosphere. The dipole moment of these chemicals was found to have a strong impact on the magnitude of the sensor response, which increas ... [Appl. Phys. Lett. 102, 173103 (2013)] published Mon Apr 29, 2013.
