The Molecular Junction Database (MJD) is a searchable resource for researchers working in molecular electronics. In general, a paper is included if it studies, measures, models, or enables charge transport in a system that can reasonably function as a molecular junction.

​​

Included Papers

​

Included studies typically involve:

• Experimental single-molecule conductance measurements (STM-BJ, MCBJ, electromigrated junctions, etc.)

• Experimental large-area conductance measurements (CP-AFM, EGaIn, etc.)

• Tunneling or transport spectroscopy through molecule-containing junctions

• Theory, calculations, or models describing explicit molecular junctions

 

Excluded-Category Papers

​

Some scientifically adjacent studies relevant to molecular electronics or molecular junction research are tracked separately from the core molecular junction dataset. These papers remain searchable through the excluded-category filters. They are relevant to molecular junction science but do not meet the criteria for inclusion in the core molecular junction dataset.

​

These excluded categories include:

• Reviews, perspectives, and editorials without new molecular junction data

• Molecular wire or device synthesis without conductance measurements

• Molecular interface studies without junction transport measurements (e.g., self-assembled monolayers)

• Scanning probe imaging or surface characterization studies without transport or tunneling spectroscopy measurements

• Atomic junction or nanogap studies without molecules

• Extended molecule-based materials lacking explicit molecular junction architectures

• Theory or modelling studies lacking a clearly defined molecular junction system

 

Excluded-category datasets are not necessarily comprehensive and may therefore be selectively indexed. Reviews, perspectives, and editorials related to molecular electronics are tracked more systematically due to their broader relevance for literature discovery.

 

Excluded Entirely

 

Studies with no meaningful molecular transport, molecular junction, or molecular-electronics relevance are excluded entirely from standard and category-expanded searches, although they may still be retrievable through exact DOI searches.​

​

Examples of topics that are generally excluded entirely include:

• Organic electronic devices (OLEDs, OFETs, OPVs, etc.)

• Batteries and energy-storage materials

• Surface-science studies lacking molecular-electronics relevance

​

If you are unsure whether a paper falls within scope, we encourage submission.

Search Functionality

 

Currently, the database supports paper-level searching, including keyword searches across titles and abstracts. Search results can be further refined using authors, journal, publication year, DOI, excluded-category, and open-access filters.
 

Future releases aim to incorporate molecular structure and substructure search functionality.

 

Errors or Omissions
