A molecular beam epitaxy machine (IMAGE) DOE/Argonne National Laboratory Caption A molecular beam epitaxy machine grows new materials one atomic layer at a time with extreme purity. MBE enables the development of devices that require negligible impurities and an extreme level of precision, such as for quantum technology and next-generation optoelectronics.
