About 2DMMS
Open-source platform for aunotnomous robotic searching and assembly of van der Waals heterostructures. The softwre is dedicated to minimize the human intervention involved in fabrication of van der Waals heterostructures. Using the software in combination with the hardware provides the following functionalities:
- Automated searching for atomically thin exfoliated 2D crystals on SiO2/Si substrate
- Building the database of opitcal microscope images of detected 2D crystals
- Computer assisted design of van der Waals heterostructures by selecting the 2D crystals from the database
- Semi-automated assembly of designed van der Waals heterostructures
License
- The software is licenced under BSD-3-Clause License
