  In this study, a newly pillared black phosphorene hybrid nanostructures (PBP)
is constructed with its thermal stability as well as thermal conductivity are
studied by performing equilibrium molecular dynamics simulation (EMD). The
results show that the curvature of the nanotube and the intense thermal
vibration of the atoms are responsible for the failure of PBP at finite
temperature simultaneously. The calculation of normalized HCACF and running
thermal conductivities (RTC) as a function of correlation time demonstrate that
thermal conductivities decreases with the temperature significantly, which is
attributed by phonon coupling and scattering from phonon spectrum analyzing.
Our result indicates that the thermal conductance of pillared black phosphorene
is comparatively low as to that of pillared graphene, black phosphorous, and
black phosphorus nanotubes, which may be promising for applications of some
specific low dimensional nanostructure based thermal and nanoelectronic
devices.
