Overview

LanTraP is a tool for calculating semi-classical thermoelectric and electronic transport properties using a Landauer transport formulation expressed in terms of the distribution of modes (DOM). It is conceptually similar to Boltzmann approaches and can be driven by band-structure inputs, enabling band-counting and mode-based analysis of thermoelectric performance.

Scientific domain: Thermoelectrics, electronic transport
Target user community: Researchers needing Landauer/DOM-based transport analysis from band structures

Theoretical Methods

• Landauer transport theory for bulk-like transport coefficients
• Distribution of modes (DOM) based transport integrals

Capabilities (CRITICAL)

• Seebeck coefficient
• Electrical conductivity (model/workflow dependent)
• Electronic thermal conductivity (model/workflow dependent)
• Mode-resolved analysis via DOM

Inputs & Outputs

• Input formats: Band structure and mean-free-path/backscattering inputs as required by the tool
• Output data types: Transport coefficients and intermediate DOM quantities; tabulated outputs

Interfaces & Ecosystem

• Often used with first-principles band structures as inputs

Limitations & Known Constraints

• Availability and exact usage depend on the distribution channel (nanoHUB) and provided interfaces.
