Microscale memory characteristics of virus-quantum dot hybrids

An electrical multi stability effect was observed for a single layer device fabricated, comprising a hybrid virus-semiconducting quantum dot ( Cd Se ∕ Zn S core/shell Qds) assembled onto icosahedral-mutant-virus template (CPMV-T184C). A substrate based bottom-up pathway was used to conjugate two dif...

Description
Summary:An electrical multi stability effect was observed for a single layer device fabricated, comprising a hybrid virus-semiconducting quantum dot ( Cd Se ∕ Zn S core/shell Qds) assembled onto icosahedral-mutant-virus template (CPMV-T184C). A substrate based bottom-up pathway was used to conjugate two different color emitting Qds for fluorescence visualization and to insert a charging/decharging factor. Pulsed wave measurements depicted distinct conductive states with repeatable and nonvolatile behavior as a functioning memory element.
