1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

In the present work, the optoelectronic properties of InP and InN alloys doped with Mg through substitution of indium atoms (with an Mg concentration of [Formula: see text]) have been investigated using density functional theory within the generalized gradient approximation. To assess the experimental feasibility of these alloys, their structural, thermodynamic, and dynamical stability were examined through cohesive energy, formation enthalpies, and phonon calculations. The calculated electronic density of states revealed band gaps of 1.27 and 0.55 eV for InP and InN, respectively. Moreover, in the Mg-doped alloys, the Fermi level crosses the electronic states, suggesting a metallic-like behavior. In addition, a gap-like separation is observed within the conduction band for both systems, indicating a redistribution of unoccupied electronic states after alloying. The maximum absorption coefficients for InP, InN, In[Formula: see text]Mg[Formula: see text]P, and In[Formula: see text]Mg[Formula: see text]N were found to be 1.42 × 10[Formula: see text] m[Formula: see text] (at 6.31 eV), 1.95 × 10[Formula: see text] m[Formula: see text] (at 5.96 eV), 1.48 × 10[Formula: see text] m[Formula: see text] (at 7.36 eV), and 1.62 × 10[Formula: see text] m[Formula: see text] (at 6.19 eV), respectively. These results suggest that the studied compounds are possible absorbers in the ultraviolet region. Furthermore, InP and InN are possible candidates for solar cell and photocatalytic applications, respectively, due to their favorable band gaps and strong absorption coefficients, while their Mg-doped counterparts may be useful for plasmonic applications.
