This dissertation examines the importance of open-sourced scientific instrumentation in two-dimensional (2D) material research. 2D materials are gaining attention due to their extraordinary electrical, mechanical, optical, and thermal properties and their potential to transform various fields. However, studying these materials often requires complex and expensive scientific instrumentation, which can limit the accessibility and progress of research. The study explores the potential of open-source software and hardware in scientific instrumentation, and its role in democratizing access, fostering collaboration, and accelerating innovation.

The study presents two instruments implemented for 2D material research, using only open-source software and hardware, and demonstrates experiments conducted with these instruments. Additionally, the study explores broader implications of open-sourced scientific instrumentation by demonstrating a motorized variable filter stage and retractable leadless pacemaker. The dissertation concludes by emphasizing the critical role of open-source instruments in the advancement of material science and the broader scientific community and the need for ongoing support and engagement to fully realize their potential.
