- The First Nano research team can develop other nanowires synthesis on our EasyWire system
- First Nano also provides assistance to customers on new process development
10. What is the difference between EasyTube™ 2000 and EasyTube™ 3000 system?
Both ET2000 and ET3000 are modular system with multiple options.
- ET2000 is a three inch tube system with smaller footprint
- ET3000 is larger than the ET2000 and can be equipped with:
- Loadlock
- Five inch process tube
11. What is the throughput of an EasyTube system?
- A complete run includes these steps:
- Purge with Argon (Ag) or evacuate to base pressure if you have the vacuum option
- Heating to growth temperature
- Processing at growth temperature
- Cooling
- Most systems take 3 hours or more for the furnace to cool down from 900 °C to 50 °C.
- The EasyTube system uses a unique design that allows the furnace to automatically open during the cool down stage reducing the time to less than an hour and total process time to 90 to 120 minutes.
- In the EasyTube™ 3000 system equipped with a Loadlock, the sample can be unloaded from the process tube at full temperature and cooled inside the Loadlock while keeping furnace at high temperature. It saves both cooling time and furnace heating time. A complete process can be finished within one hour.
