W2: Carbon as the Conductor material (and potentially resistors, capacitors and inductors) Step 1: Put a wire on a substrate (paste or liquid preferable to powder)
W1: document material and process choice, investigate printing, inert substrate
Materials and Processes
| Material | Doping Process | Notice |
|---|---|---|
| Silicon | Mix in during boule creation and ion implantation (particle acceleration with phosphorus or arsenic and boron or gallium) or furnace with gas (diffusion) | Need at least 10 kEv. Heat treatment for recrystallization (electrical activation) afterwards. Silicon dioxide mask for gas |
| Organic semiconductors | Beaker chemistry, dissolve into solvent | |
| Graphene | Doping during furnace and gas formation | |
| Zinc sulfide | ||
| 2-6 semiconductors | Beaker chemistry, small particle slurry |
Conductor
- Carbon, gold don't oxidize
- Aluminum, silver, copper
Recycling
- Electroplating to recover metals (different voltages for different metals)/
- Size-selective precipitation technique if p, n had different sizes
- Selective etches
- Focused ion beams to bombard off surface
