Q2. What was the process of graphene growth?
Graphene growth was carried out in a vertical cold wall reactor comprised of a doublewalled quartz tube and a graphite susceptor in a moderate flow of argon (5.0).
Q3. What was the first step in the graphene growth?
Electrical measurements in van der Pauw geometry or on Hall bar structures were carried out in a continuous flow cryostat (sample in vacuum), using magnetic fields of ±0.66 T at temperatures between 300 and 25 K.The authors gratefully acknowledge support by the DFG under contract SE 1087/5-1, contract WE45425-1, and within the Cluster of Excellence ‘Engineering of Advanced Materials’ (www.eam.unierlangen.de) at the Friedrich-Alexander-Universität Erlangen-Nürnberg, and the BMBF under contract 05 ES3XBA/5.
Q4. What was the first step of the graphene etching?
A second step defined the contact pads, which consist of thermally evaporated Ti/Au double layer, patterned by a standard lift-off technique.
Q5. What was the reaction temperature of graphene?
A wide range of annealing temperatures from 1500 to 2000° C and reactor gas pressures from 10 mbar to 900 mbar were tested and a detailed account of all observations will be provided elsewhere.
