The Molecular Junction Database (MJD) is a searchable resource for research in molecular electronics and charge transport through molecular junctions. The field now comprises an estimated 2,000-2,500 publications worldwide, spanning chemistry, physics, materials science, nanotechnology, and related disciplines.
In general, a paper is included in the database if it studies, measures, models, or enables charge transport in a system that can reasonably function as a molecular junction.
Included studies typically involve:
-
Experimental single-molecule conductance measurements (STM-BJ, MCBJ, etc.)
-
Experimental large-area conductance measurements (CP-AFM, EGaIn, etc.)
-
Theory, calculations, or models of explicit molecular junctions
Some scientifically adjacent papers are also tracked but categorized separately. As these do not comprise studies of explicit molecular junctions, they are not included as part of the core molecular junction dataset. However, they remain useful for literature discovery and can optionally be included in searches using the excluded-category filters.
These excluded categories include:
-
Reviews, perspectives, and editorials
-
Molecular wire/device synthesis without conductance measurements
-
Self-assembled monolayer (SAM) studies without conductance measurements
-
Scanning probe microscopy/imaging studies without conductance measurements
-
Atomic junctions without molecules
-
Theory/model transport studies that do not describe an explicit molecular junction
Studies with no transport or molecular junction relevance are excluded entirely from standard and category-expanded searches, although they may still be retrievable through an exact DOI search.
Currently, only paper-level information is searchable, including title, abstract, year, authors, DOI, and journal. Incorporation of molecular structure search functionality is planned for future releases.
Any indexing errors or omissions can be reported directly from an article page, accessible through the “View Details” link for each search result.
If you are unsure whether a paper falls within scope, we encourage submission.
