Abstract
A molecular layer includes a Langmuir-Blodgett (LB) film of a molecule connected to a plurality of active device molecules, the molecule having a moiety with first and second connecting groups at opposed ends of the moiety. Each of the plurality of active device molecules includes a switching moiety, a self-assembling connecting group at one end of the switching moiety, and a linking group at an opposed end of the moiety. One or more defect site(s) exist between the plurality of active device molecules. A respective number of the first connecting groups of the LB film are connected to the plurality of active device molecules via at least some of the linking groups such that the LB film covers the plurality of active device molecules and the one or more defect site(s).

A method of forming a molecular layer, comprising the steps of:
- chemically bonding a self-assembled molecular film to a surface of a substrate, the self-assembled molecular film including at least one defect site and a plurality of active device molecules, each of the plurality of active device molecules including a molecular switching moiety having a self-assembling connecting group at one end of the moiety and a linking group at an opposed end of the moiety;
- forming a Langmuir-Blodgett (LB) film of a molecule on at least one of a water/solvent interface and an air/water interface, the molecule including a moiety having first and second connecting groups at opposed ends of the moiety;
- and
- connecting the LB film to at least some of the linking groups of the plurality of active device molecules via a respective number of the first connecting groups, wherein the LB film covers the plurality of active device molecules and the at least one defect site, thereby forming the molecular layer.

- chemically bonding the self-assembled molecular film to the surface of each of the plurality of bottom electrodes;
- forming a Langmuir-Blodgett (LB) film of a molecule on at least one of a water/solvent interface and an air/water interface, the molecule including a molecular switching moiety having first and second connecting groups at opposed ends of the moiety;
- connecting the LB film to at least some of the linking groups of the plurality of active device molecules via a respective number of the first connecting groups, wherein the LB film covers the plurality of active device molecules and the at least one defect site;
- and
- forming one of the plurality of top electrodes, crossing the one of the plurality of bottom electrodes at the non-zero angle, thereby forming the at least one junction therebetween, wherein the LB film is chemically bonded on a surface of the one of the plurality of top electrodes.
