Abstract:

Recently, graphene; a single layer thick two dimensional honey comb lattice of sp2 carbon atoms, has been the focus of a vast amount of researches due to its unique properties such as high carrier mobility and high transparency. The superior characteristics are fundamentally available in various device applications such as solar cells, light emitting diodes, terahertz plasmon oscillators and so on.
To realize high-performance graphene-based devices, two fundamental issues should be solved. The first is to transfer high-quality graphene layers from growth substrate to target substrate without any occurrence of chemical residues (of a carrier layer), wrinkles, and cracks. The second is to change the electrical polarity of the transferred graphene layer easily. Satisfying both issues at a same time is technologically desirable. Thus, in this presentation a novel technique that can provide a simultaneous graphene transfer and electrical polarity change by using nitrocellulose, and a device application of this transfer technique will be presented.
