  Trapped atoms on photonic structures inspire many novel quantum devices for
quantum information processing and quantum sensing. Here, we have demonstrated
a hybrid photonic-atom chip platform based on a GaN-on-sapphire chip and the
transport of an ensemble of atoms from free space towards the chip with an
optical conveyor belt. The maximum transport efficiency of atoms is about 50%
with a transport distance of 500 $\mathrm{\mu m}$. Our results open up a new
route toward the efficiently loading of cold atoms into the evanescent-field
trap formed by the photonic integrated circuits, which promises strong and
controllable interactions between single atoms and single photons.
