Definition Silicon, atomic number 14, has 24 known isotopes with mass numbers ranging from 22 to 45. Silicon has three stable isotopes: 28 Si with 92.23 % abundance, 29 Si with 4.67 % abundance, and 30 Si with 3.1 % abundance. Introduction As the second most abundant element on Earth, ...
Silicon has a suitable bandgap (1.1 eV), elemental abundance, and high thermal stability for electronic and catalytic applications27,28,29,30,31,32,33. The rigid diamond-type structure of silicon tends to expel dopant elements during crystal formation at high temperatures, yielding low concentr...
Silicon is the most widely used semiconductor material in the electronics industry. Its popularity can be attributed to several factors, including its abundance in the Earth's crust, its ability to form high-quality insulating oxide layers, and its compatibility with various fabrication processes. Sil...
Silicon (Si) due to its ultrahigh theoretical capacity (4200 mAh g−1) [2], low charge-discharge potential (<0.5 V) [3] and abundance on Earth (~27%) [4] have been considered to be the most hopeful alternative anode material for the new lithium-ion batteries [5], [6]. ...

Owing to the abundance of silicon in the Earth's crust, natural silicon-based materials have been used for thousands of years. Silicon rock crystals were familiar to various ancient civilizations, such as the predynastic Egyptians who used it for beads and small vases, as well as the ancient ...
(Ru) essentially reside in planetary cores such that their depleted abundance in the silicate portion of rocky bodies documents only the final stage of a planet’s accretion5. Moreover, siderophile elements are strongly affected by metal–silicate equilibration associated with the Moon-forming impact...
