  In this work we study sulfur confined between two multilayer graphene films
under thermal treatments by means of electrical and Raman spectroscopy
characterization. We found some similarities between the electrical behavior
and differential scanning calorimetry of sulfur immersed into nanoporous anodic
alumina template during sulfur phase transitions, this suggests that sulfur has
a different thermal behavior when it is in confining conditions compared to the
free state. In addition, multilayer graphene was exposed to sulfur vapors at
500 {\deg}C to induce chemical reaction. This method effectively produced
covalent bonding between sulfur and multilayer graphene and a p-type doping of
about 2x10^13 cm^-2 in charge concentration. Finally, based on first principle
calculations we speculate on the existence of a new bidimensional structure of
sulfur.
