OpenSTM is an open-source DIY scanning tunneling microscope (STM) project capable of atomic-scale imaging, demonstrated by resolving carbon atoms in highly oriented pyrolytic graphite (HOPG). It includes 3D models, PCB designs, ESP32 firmware, and a Python host application, and has been published in the journal HardwareX.
Use cases
- build a DIY scanning tunneling microscope
- image atoms of HOPG at home
- measure tunneling distance-current curves
- perform scanning tunneling spectroscopy (STS)
- learn open-source scientific instrument design
- replicate a published low-cost STM design
When to choose
- you want a low-cost, documented open-source STM with proven atomic imaging results
- you need complete design files: 3D models, PCBs, firmware, and host software
- you want a design backed by a peer-reviewed HardwareX publication
When to avoid
- you need a commercial-grade, turnkey microscope with support and calibration guarantees
- you cannot do CNC machining, PCB assembly, or vibration isolation work
- you need fast, high-resolution imaging beyond what a hobbyist STM can achieve
