Develop and audit Bi2Te3-family flexible thermoelectric films and devices, including deposition or printing, composition and texture, substrate and interface mechanics, p/n integration, wearable thermal boundaries, bending reliability, metrology, and device benchmarking; use when Bi2Te3, Sb2Te3, flexible thin films, conformal generators, cooling patches, fibers, textiles, or bend-cycle failures are central.
Engineer and audit GeTe-based thermoelectric materials and devices across defect chemistry, carrier concentration, band and phase engineering, phonon scattering, synthesis, temperature-dependent transport, contacts, diffusion barriers, legs, modules, and reliability; use when GeTe composition, Ge vacancies, rhombohedral-cubic transition, band convergence, average zT, junctions, or mid-temperature module performance is central.
Route and execute rigorous thermoelectric semiconductor and device research, including field mapping, transport-physics reasoning, literature audits, hypotheses, experiment design, metrology, uncertainty, materials-to-device translation, and failure analysis; use for broad thermoelectric questions spanning materials, contacts, modules, cooling, or power generation, and route flexible Bi2Te3 or GeTe work to their dedicated Skills.

End-to-end: topic/keywords/DOI in → validated PDF files out. One pipeline, two interchangeable search backends, a layered download strategy, and concurrency.
Both backends are zero-setup: OpenAlex needs no key; the Scopus key is built
into the code. The only thing the operator must provide is UNPAYWALL_EMAIL.
Follow this top-down. Each step says which script and why.
Default to OpenAlex end-to-end → skills/sci-papers-downloder/scripts/openalex_batch_download.py.
Free, no key, ~250M works, returns metadata and a direct OA PDF hint.
This is the right choice for ~95% of "find and download papers on X" requests.
Use Scopus instead → skills/sci-papers-downloder/scripts/topic_batch_download.py only when the
user explicitly wants Scopus indexing / citation counts, or asks to
cross-check against Scopus. Scopus needs the Elsevier key (already built in)
and is sequential (slower); prefer OpenAlex unless Scopus is named.
Already have DOIs? Skip search → skills/sci-papers-downloder/scripts/download_open_access.py
(--doi repeatable, or --doi-file). This is the shared downloader both
end-to-end runners call.
Search without downloading? → skills/sci-papers-downloder/scripts/search_openalex.py (no key) or
skills/sci-papers-downloder/scripts/search_scopus.py (key built in).
For each DOI the downloader tries, in order, and stops at first valid %PDF:
oa_url hint from search) — highest hit rate.scihub-cli — on by default (--scihub-fallback auto).
Recovers older closed-access papers Unpaywall can't.The only required env var is the contact email (also used for the OpenAlex polite pool):
export UNPAYWALL_EMAIL="<your_real_email>" # required for OpenAlex + Unpaywall
Already wired in, no action needed:
search_scopus.py
(DEFAULT_ELSEVIER_API_KEY). Override anytime via --api-key or
ELSEVIER_API_KEY. Rotated periodically by the operator.scihub-cli on PATH (or it
auto-bootstraps via uvx). Disable per-run with --scihub-fallback off.This is the deterministic mapping from Chinese phrasing to flags.
--quantity-mode few (target ~5)--quantity-mode batch (target ~20)--quantity-mode max (high caps, bounded runtime)--target 12 (overrides quantity mode)--quantity-mode batch--latest (last 3 years + date-first sort)--latest --years-back N--from-year 2023--quantity-mode batch --latest--quantity-mode few --latest--target 8 --latest--target > quantity keywords--from-year > --years-back--latest implies date-first rankingpython3 skills/sci-papers-downloder/scripts/openalex_batch_download.py --keywords "pedestrian simulation" --quantity-mode batch --latest --concurrency 8 --outdir ./downloads
Flags worth knowing:
--concurrency N — parallel downloads, default 8. Polite range 8–16; higher
gets rate-limited by OpenAlex/Unpaywall.--oa-only is on by default (most reliable). --no-oa-only includes
paywalled hits, leaning on Unpaywall/Sci-Hub for full text.--scihub-fallback {auto,off,force} — default auto. off = OA/Unpaywall
only; force = skip Unpaywall, go straight to Sci-Hub.--scihub-timeout S — per-DOI Sci-Hub budget (default 180). Lower it (e.g. 60)
when many closed DOIs would otherwise serialize long waits.python3 skills/sci-papers-downloder/scripts/topic_batch_download.py --keywords "pedestrian simulation" --quantity-mode batch --latest --outdir ./downloads
