1.	ANDERSSON, MICHAEL, 1988, et al. (author) Microwave characterization of Ti/Au-graphene contacts 2013 In: Applied Physics Letters. - : AIP Publishing. - 0003-6951 .- 1077-3118. ; 103:17, s. 173111- Journal article (peer-reviewed)abstract In this paper, we report on a microwave characterization of the interface between Ti/Au contacts and chemical vapor deposition graphene using structures of Corbino geometry, with primary focus on extracting and modeling the capacitance associated with the contact region. It is found that with the current contact resistivity, ρc∼10^−6 Ωcm2, the contact capacitance, on the order Cc∼1 μF/cm2, has a negligible effect on microwave transmission through the contact below ∼100 GHz. Finally, a parallel plate capacitance model for the contact is presented.
2.	ANDERSSON, MICHAEL, 1988, et al. (author) Towards Graphene Electrodes for High Performance Acoustic Resonators 2013 In: WOCSDICE. ; , s. 99-100 Conference paper (peer-reviewed)abstract The tunable FBAR is a promising building block for versatile microwave systems. Utilizing graphene electrodes promises higher tunability and frequency. Increased parasitic resistance may hamper the Q-factor of the resonator. This paper reports the initiated study of graphene and contacts at DC and microwave frequencies for optimization of these parameters leading to graphene FBARs.
