In the proposed structure, the nanostring interacts dispersively and reactively with the microdisk cavity via the evanescent field. We study the role of both dispersive and reactive coupling in generating optomechanical entanglement, and show that the room-temperature entanglement can be effectively obtained through the dispersive couplings within the reasonable experimental parameters. In particular, we find, in the high Temperature (\$T\$) and high mechanical qualify factor (\$Q\_m\$) limit, the logarithmic entanglement depends only on the ratio \$T/Q\_m\$. This means that improvements in the material quantity and structure design may lead to more efficient generation of stationary high-temperature entanglement.
