In this paper, we propose a new
contextualization of the so-called scientific method in teaching practices in
science and engineering education. We report an objectification in information
and communication technologies (ICT) for simulate the reaction rates during an
class and its inclusion in the above-mentioned pedagogical purpose, that, in
tune with the current realities of schools, rehearses reflections of a future
with another horizon for teaching/learning engineering and other sciences.
We have developed a dry transfer method that allows graphene to be transferred from polymer- thyl-methacrylate (PMMA)/Si (silicon) substrates on commercially available hexagonal boron ni- tride (hBN) crystals. With this method we are able to fabricate graphene devices with little wrin- kles and bubbles in graphene sheets, but that do not degrade the electronic quality more than the SiO2 substrate does. For hBN to perform the function described above substrate cleanliness is critical to get high quality graphene devices. Using hBN as a substrate, graphene exhibits enhanced mobility, reduced carrier inhomogeneity, and reduced intrinsic doping compared to graphene on SiO2 substrate.
