The Feasibility of Atomic-Scale Memory from BCC Crystal

FAN Kang-qi,JIA Jian-yuan,ZHU Ying-min (School of Electro-Mechanical Engineering,Xidian University,Xi'an 710071,China)  
Molecular dynamics simulations were performed to research the atomic behaves in the surface and deeper layers of body-center cubic(BCC)crystal,with Morse potential denoting the interactions among the atoms. The results indicate that BCC crystal maintains stable before and after the central atom is manipulated. That is BCC crystal holds the property of double steady states,which is capable of representing'0'and'1'. At the same time,many-atomed combination of double steady states was investigated by means of molecular dynamics simulations method. In the case of many-atomed combination of double steady states,BCC crystal still remains stable when manipulating other central atoms. Based on the facts given above,a novel way to achieve atomic-scale memory is put forward,which has the advantages of high speed,better veracity and repetitiousness.
