“…In this context, one promising technique for the nanopositioning of such quantum emitters is AFM-nanoxerography [30][31][32][33][34][35][36][37]. This technique consists in the electrostatic directed assembly of colloidal nanoparticles (NPs) on charge patterns generated by electrical injection with a polarised AFM tip in a poly(methyl methacrylate) (PMMA) film used as an electret.…”

“…This approach is very versatile since the desired geometry of charge patterns can be easily modified and implemented in a script guiding the AFM tip movement. Nanoxerography allows to realise NP assemblies over a variety of electrets and substrates [30,31,[36][37][38][39]. It can be applied to any kind of charged and/or polarisable colloidal NPs [30,33,37], but until now it has not been used to assemble SPEs and NDs specifically.…”

It can be applied to any kind of charged and/or polarisable colloidal NPs [30,33,37], but until now it has not been used to assemble SPEs and NDs specifically. Moreover, whereas this technique has been mostly used for NP assemblies on micrometric patterns, there are few reports on its application to nano-positioning of single colloidal nano-objects [40][41][42].…”

Atomic force microscopy (AFM) nanoxerography was successfully used to direct the assembly of colloidal nanodiamonds (NDs) containing nitrogen-vacancy (NV) centres on electrostatically patterned surfaces. This study reveals that the number of deposited NDs can be controlled by tuning the surface potentials of positively charged dots on a negatively charged background written by AFM in a thin PMMA electret film, yielding assemblies down to a unique single-photon emitter with very good selectivity. The mechanisms of the ND directed assembly are attested by numerical simulations. This robust deterministic nano-positioning of quantum emitters thus offers great opportunities for ultimate applications in nanophotonics for quantum technologies.

Achieving high-resolution and cost-effective microdisplays for augmented and virtual reality applications now requires shaping the color conversion quantum-dot-based layers into structures corresponding to micropixels. We propose herein an alternative and versatile approach for addressing this challenge, nanoxerography, an electrostatic-based technique to selectively direct the assembly of colloidal nano-objects on precisely chosen areas of electrets. Coassembly of red- and green-emitting core–shell Cd(Se,S)/(Cd,Zn)S quantum nanoplatelets was performed on passive (PMMA/ITO/glass) and active (PMMA/ITO/GaN μLEDS) substrates. Topographical, optical, and electro-optical characterizations were further realized. Lateral resolution for subpixels of 800 nm (using charge injection by atomic force microscopy) and 3 μm (using charge injection by electrical microcontact printing) over surfaces larger than 1 cm2 in the later case was demonstrated. Nanoxerography was also proven to not alter the optical properties of the assembled quantum nanoplatelets. Without even the need of optical black barriers, no crosstalk between quantum nanoplatelet-based subpixels was observed for interspace greater than 1 μm. Red emitting quantum nanoplatelets assembled as 7.5 μm squared subpixels on active GaN blue-lit active substrates give an external quantum efficiency and internal quantum efficiency of 7.5 and 17%, respectively.
