Epi-ready CMP-polished magnesium oxide (MgO) Single-Crystal substrates (MgO, CAS 1309-48-4) wafers and diced research squares with sub-nanometer surface roughness for PVD, PLD, MBE, and ALD.
Precision-grown and chemical-mechanical-polished (CMP) in a Class 100 cleanroom, our magnesium oxide (MgO) Single-Crystal substrates (MgO, CAS 1309-48-4) substrates provide atomically smooth, epi-ready surfaces (Ra < 0.2–0.5 nm) for thin-film epitaxy, pulsed laser deposition (PLD), magnetron sputtering, molecular beam epitaxy (MBE), and optical characterization.
With its cubic rock-salt lattice parameter (a = 4.212 Å) and low dielectric loss, single-crystal MgO is the standard substrate for Fe/CoFeB/MgO magnetic tunnel junctions, YBCO high-Tc superconductors, and ferroelectric perovskite films. Standard research sizes include 5×5 mm, 10×10 mm, and 15×15 mm diced squares (0.5 mm or 1.0 mm thick) as well as Ø 1-inch, 2-inch, 3-inch, and 4-inch wafers in single-side (SSP) or double-side (DSP) polished finishes, packed in individual waffle trays or nitrogen-sealed cassettes with batch orientation and surface inspection data.
