source-reported / not adjudicatedRelease 26b49bcd0ed8, released 11 September 2026Turn on scripting to keep a reference with an investigation.
Shown as the publication reported them. Nothing here has been adjudicated, corroborated against another source, or promoted to an accepted conclusion.
What this publication reports
4 values across 2 properties and 1 served specimen, at stated temperatures from 300 to 1000 K.
Seebeck coefficient (2), Figure of merit zt (2).
The publication's own wording is the fourth column, past the edge of this screen: the table scrolls sideways inside its box and the property stays in place while it does.
| Property | Value, as served | Condition | As the publication words it |
|---|---|---|---|
| S_pi_snse_crystal4 values. Made in step 1, structural optimization. | |||
| Seebeck coefficientC1 | 0.00016152 V/K | 1000 K | The maximum value of the Seebeck coefficient of 161.52 μV·K−1 is obtained for the π-SnSe alloy at the highest temperature (1000 K). |
| Figure of merit ztC3 | 0.76 dimensionless | 1000 K | At room temperature, a ZT value of 0.74 is obtained which slightly increases with the temperature increase, reaching its maximum value of 0.76 at 1000 K. |
| Figure of merit ztC4 | 0.74 dimensionless | 300 K | For the studied material, a ZT value of 0.74 is achieved at room temperature. |
| Seebeck coefficientC5 | 0.00014637 V/K | 300 K | At room temperature, the Seebeck coefficient and power factor have values of 146.37 µV·K−1 and 0.63 ×1011 W·K−2·m−1·s−1, respectively. |
A condition is the temperature a value was published under, as this release states it. Rows are in served order: nothing is ranked, converted or joined into a curve, and a shared property does not make two rows comparable.
Nothing is recorded against the values this release published. That is not a statement that none exist.
How the specimens were prepared
The record's own steps, in order, each with the passage it was read from.
structural optimization
No input specimen servedproducesS_pi_snse_crystal
We started from experimentally reported atomic positions and performed structural optimizations by varying the volume until the minimum energy was reached.
One value, in full
Reading C4 of 4 published values. Pick another row above; this link opens exactly this value.
Interpretation
Figure of merit zt
0.74dimensionlessat 300 K
A dimensionless quantity. The normalized unit 1 is correct and derived; the source printed no unit characters for it to be read from, which is why its unit is unavailable below rather than verified.

into the active investigation
As the publication words it
For the studied material, a ZT value of 0.74 is achieved at room temperature.
Unit and where it came from
- Normalized unit
- Dimensionless (UCUM 1)
- Unit provenance
- Not read from the source
A normalized or derived unit may still be correct. What this says is that the source supplied nothing the unit could be bound to.
a dimensionless quantity prints no unit surface beside its value; what follows it here is a condition or prose, and the resolved unit is legitimately derived, not read
This is not missing data. A dimensionless quantity has no unit characters to print beside its value, so the normalized unit is legitimately derived rather than read from the page.
How the value was normalized
none (reported unit retained); profile unit table
Source wording grouped for this value
No grouping was released for this value. It is not reconstructed from nearby text.
Exactly as this release served them. Not a score, and not a statement that the publication's own reading is correct.

What this record did not publish
1 of 5 claim entries were withheld, each with the reason the compiler recorded. A withholding is a typed result, not a gap in this page.
The claim this release withheld

|---|---|---|
| C2 | component_support: scientifically unsupported: temperature_k: the retained passage states its sole temperature in kelvin as '1000', not the '300' this reading is published under; the passage also says room temperature, which the stated room-temperature rule reads as 300 K only where the passage prints no temperature in kelvin | Candidate structured value, withheld Withheld, not published Figure of merit zt 0.74 dimensionless at 300 K Candidate wording At room temperature, a ZT value of 0.74 is obtained which slightly increases with the temperature increase, reaching its maximum value of 0.76 at 1000 K.

A claim withheld because its passage does not support a component keeps the candidate the extraction proposed beside the retained passage; the candidate is what the record could not fully support, never a value this release published.
How this record was built
The source was retained and candidate claims were read out of it. Of the 16 parts its published values could carry evidence for, 14 could be checked back against the retained page. Each step's quantity is drawn from the one above it.
The retained source
This release retained 4 source artifacts. Every passage on this page is read from those bytes and from nothing else.

Counts describe scope. They are not a confidence score, and a larger number does not make a value stronger. Each figure counts claim entries the release served, one per claim id, not distinct scientific findings: two entries may report the same value, and both are kept with their own id, evidence and disposition rather than merged or judged to be one finding.
How much of each value is anchored
