Spectral Current Density and Responsivity Scaling for Fourier Transform Photocurrent Spectroscopy
Jan Kunc, Bohdan Morzhuk, Mykhailo Shestopalov +2
We propose and experimentally verify two methods to scale arbitrary units to photocurrent spectral density (A/eV) in Fourier Transform Photocurrent (FTPC) spectroscopy. We also pro…
Intercalation of hydrogen in the SiC/epitaxial graphene interface
Jan Kunc, Martin Rejhon, Pavel Hlídek
We have measured optical absorption in mid-infrared spectral range on hydrogen intercalated epitaxial graphene grown on silicon face of SiC. We have used attenuated total reflectio…
The electroluminescent properties based on bias polarity of the epitaxial graphene/aluminium SiC junction
M. Rejhon, J. Franc, V. Dědič +2
We investigated the electroluminescent properties of the epitaxial graphene/SiC junction. The temperature and current dependence of electroluminescence from the epitaxial graphene/…
Effect of residual gas composition on epitaxial graphene growth on SiC
Jan Kunc, Martin Rejhon, Eduard Belas +3
In recent years, graphene growth optimization has been one of the key routes towards large-scale, high-quality graphene production. We have measured in-situ residual gas content du…
Wafer bonding solution to epitaxial graphene - silicon integration
Rui Dong, Zelei Guo, James Palmer +7
The development of graphene electronics requires the integration of graphene devices with Si-CMOS technology. Most strategies involve the transfer of graphene sheets onto silicon,…
A method to extract pure Raman spectrum of epitaxial graphene on SiC
Jan Kunc, Yike Hu, James Palmer +2
A method is proposed to extract pure Raman spectrum of epitaxial graphene on SiC by using a Non-negative Matrix Factorization. It overcomes problems of negative spectral intensity…
Record Maximum Oscillation Frequency in C-face Epitaxial Graphene Transistors
Zelei Guo, Rui Dong, Partha Sarathi Chakraborty +9
The maximum oscillation frequency (fmax) quantifies the practical upper bound for useful circuit operation. We report here an fmax of 70 GHz in transistors using epitaxial graphene…
