JSPM-4500A UHV AFM
MCh's AFM/STM-system is a JSPM-4500A “Ultrahigh Vacuum Atomic Force Microscope” made by JEOL. It consists out of three chambers: exchange, sample cleaning and observation chamber.
Technical Specifications
| General | JSPM-4500 | |
|---|---|---|
| Vacuum | Exchange chamber | 1*10-5 Pa |
| Sample cleaning | 5*10-7 Pa (down to 10-7 Pa) | |
| Observation chamber | < 3*10-8 Pa | |
| Pumping system | Exchange chamber | oil rotary pump + turbo molecular pump |
| Treatment chamber | sputter ion pump (SIP2) / Ti sublimation pump (TSP) | |
| Observation chamber | sputter ion pump (SIP1) / Ti sublimation pump (TSP) | |
| Vacuum gauges | Exchange chamber | Pirani/Penning gauge |
| Treatment chamber | Pirani/Penning gauge | |
| Observation chamber | nude filament (ion) gauge |
| Detection signal | JSPM-4500 |
|---|---|
| AFM contact mode | 10 pN up to 10nN |
| Tunnelling current (STM mode) | 50 pA up to 1µA |
Currently, the AFM/STM has not been used for a while. An AFM/STM-training is considered for some MCh staff.
