Table 4 Comparison of different patterning techniques for QD deposition
From: Micro-light-emitting diodes with quantum dots in display technology
Patterning technique | Pattern linewidth | QD film thickness |
|---|---|---|
Photolithography | Several µm | Several µm |
Electron-beam lithography | Several nm | ~10 nm |
Inkjet printing | 250 nm | Several µm |
Microcontact printing | Several dozens nm | Monolayer |
3D printing | A few µm | N/A |
