Abstract: A silicon wafer, a preparation method of the silicon wafer, and a passivation treatment solution is disclosed. The preparation method of the silicon wafer can include the following steps: providing a solar silicon ingot; cutting the solar silicon ingot with a first treatment solution to form a pretreated silicon wafer; degluing the pretreated silicon wafer with a second treatment solution to obtain a deglued silicon wafer; and cleaning the deglued silicon wafer with a third treatment solution to obtain the silicon wafer; wherein at least one of the first treatment solution, the second treatment solution and the third treatment solution comprises a non-metallic compound that is bonded with a silicon ion via a single bond.

Abstract: Disclosed are a magnetic memory and a magnetic memory preparation method. The magnetic memory includes a heavy metal layer, a metal film layer, and a magnetic tunnel junction (MTJ) layer. The metal film layer is located between the heavy metal layer and the MTJ layer. A spin-orbit coupling effect of a material of the heavy metal layer is stronger than a spin-orbit coupling effect of a material of the metal film layer.

Abstract: A system and method for scheduling delivery of packetized data traffic at an output port of a network node featuring a hybrid queue with a unicast subqueue and a multicast subqueue. An interleave indicator for each unicast and multicast entry in the queue is used to toggle the header type field of the hybrid queue. Upon departure, a scheduler selects between the unicast subqueue and multicast subqueue as dictated by the state of the header type field. The disclosed interleave indicator techniques add minimal overhead to the system, allowing ready scaling with increasing port densities. Further, the data structure of the multicast subqueue can be selected to optimize the system and achieve desired performance characteristics.
