  In this work, we study the thermal energy transport properties of twin
graphene, which has been introduced recently as a new two-dimensional carbon
nano structure. The thermal conductivity is investigated using non-equilibrium
molecular dynamics simulation. We examine the effects of the length,
temperature, and also the uni axial strain along with both armchair and zigzag
directions. We found that the conductivity increases with growing the system
length, while that slightly decreases with increasing the mean temperature of
the system. Moreover, it is shown that the applied strain up to 0.02 will
increase the thermal conductivity, and in the interval 0.02-0.06, it has a
decreasing trend which can be used for tuning the thermal properties. Finally,
the phonon density of states is investigated to study the behavior of thermal
conductivity, fundamentally. We can control the thermal properties of the
system with changing parameters such as strain. Our results may be important in
the design of cooling electronic devices and thermal circuits.
