Project B12 aims to control the electronic transport properties of mono- and bilayer graphene and (reduced) graphene-oxide on surfaces using local and global strain. The first of two work packages, WP-1, elucidates the electronic impact of covalent and non-covalent functionalization under strain by in-operandi (opto)electrical monitoring. Exploiting the unique valley-sensitivity of graphene(mono/bi) is subject of WP-2. Here local-strain induced topological and magnetic-field imposed electronic currents are combined which allows to generate novel transport features such as charge-carrier and electric-field dependent anisotropies.

项目B12旨在使用局部和全局应变控制表面上单层和双层石墨烯和（还原）石墨烯氧化物的电子传输特性。两个工作包中的第一个WP-1通过操作中（光）电监测阐明了应变下共价和非共价官能化的电子影响。利用石墨烯（单/双）独特的谷敏感性是WP-2的主题。在这里，局部应变引起的拓扑和磁场施加的电子电流相结合，允许产生新的传输功能，如电荷载流子和电场依赖的各向异性。
