Gallium (Ga) is a post-transition metal with atomic number 31: a neutral gallium atom has 31 protons and 31 electrons. Atomic mass 69.723 u, electron configuration [Ar] 3d10 4s2 4p1. Gallium is a soft metal with an unusually low melting point that will melt in your hand.
As of 2026-09-25 · the last 10 years
Research intensity has climbed to about 96% of the element’s all-time peak, a level reached within this window.
Research intensity ran from about 63% of the element's own all-time peak in 2016 to about 96% in 2026 — a mid-window dip followed by a recovery, and the all-time peak (2025) falls inside this window. Over the same span its share of research attention across all elements rose. Among the 118 elements, gallium has a larger-than-average research literature.
The number of papers involving the element rose from about 49,915 in 2016 to about 170,059 in 2025 (3.41x). That is faster than the literature as a whole grew over the same years, so the element gained ground in the wider body of research.
The core of this literature is Wide-Bandgap Semiconductor Devices for Power Electronics, Optoelectronics and Sensing. Gallium is central to this community, with about 61% of its papers involving the element. This group accounts for about 41% of gallium’s recent research, a share that has remained steady over the last decade. The work focuses on high-performance devices, often characterized by phrases like "gan power" and "barrier diodes." A key anchor is a 2018 review of Ga2O3 materials and devices, cited over 3,100 times, alongside a 2023 text on power electronics principles, cited over 1,300 times.
A second major strand is Generative Models for Image Synthesis and Enhancement. Here, gallium is one strand of a broader community, appearing in about 21% of its papers. This community represents about 20% of gallium’s recent research, also holding steady. The connection lies in the use of conditional GANs and image super-resolution techniques, often applied to fault diagnosis or data generation. The most cited work in this area is a 2017 paper on Generative Adversarial Nets, cited over 21,000 times, while a 2022 paper on text-to-image diffusion models has been cited over 2,100 times.
A smaller but distinct area is Gallium Arsenide Nanowires and Quantum Dots in Photovoltaics. Gallium is a minor presence in this much larger community, with only about 8% of its papers involving the element. It holds about 4% of gallium’s recent research, a share that has remained steady. This work engineers gallium arsenide nanowires and quantum dots for high-efficiency solar cells, distinct from the dominant silicon focus. A 2024 evaluation of solar cell technologies, cited over 260 times, exemplifies this niche.
Overall, the composition of gallium research has remained stable, with the semiconductor and generative model communities holding their shares, while the photovoltaic niche remains a minor but consistent component. The remainder of the literature, comprising other smaller communities, accounts for about 35% of the element's recent work.
