摘　　要：Molecular field-coupled nanocomputing(molFCN)encodes information in the molecule charge distribution and elaborates it through electrostatic coupling.Despite the advantageous sub-nanometric size and low-power dissipation,only a few attempts have been made to validate the technology experimentally.One of the obstacles is the difficulty in measuring molecule charges to validate information encoding or integrate molFCN with complementary-metal-oxide-semiconductor(CMOS).In this work,we propose a paradigm preserving the advantages of molFCN,which exploits the position of waiving molecules to augment the information encoding.We validate the paradigm,named bend-boosted molFCN,with density functional theory using 6-(ferrocenyl)hexanethiol cations.We demonstrate that the encoded information can be electrically read by constituting a molecular junction.The paradigm is compatible with the charge-based molFCN,thus acting as a readout system.The obtained results favor the experimental assessment of the molFCN principle through scanning probe microscopy techniques and the design of molFCN-CMOS heterogeneous circuits.
