epitaxial wafers technical

"to lead scaling efforts for Aeluma’s large-diameter epitaxial wafers."

Epitaxial wafers are semiconductor discs where a very thin, single-crystal layer has been deliberately grown on a base substrate to create the precise electrical properties needed for modern chips, LEDs and power devices. Investors care because the quality and availability of these wafers directly affect manufacturing yield, product performance, production costs and supply-chain risk—think of them as the carefully prepared foundation that determines whether a building (or chip) is reliable and profitable.

epitaxy technical

"she led epitaxy operations and engineering through multiple stages of company growth"

Epitaxy is a manufacturing technique where a new, highly ordered crystalline layer is grown directly on top of an existing crystal so the atoms align with the underlying structure. It matters to investors because the quality and consistency of these layers determine the performance, yield and cost of semiconductors, LEDs and sensors; think of it as laying perfectly matched bricks so a device works faster, lasts longer and is cheaper to produce.

indium gallium arsenide (ingaas) technical

"Aeluma’s indium gallium arsenide (InGaAs) photodiode technology for consumer sensing"

Indium gallium arsenide (InGaAs) is a crystalline semiconductor made from indium, gallium and arsenic that is especially good at detecting near-infrared light and converting it into electrical signals. Investors track InGaAs because it is a key component in high-value products like fiber-optic communications, infrared sensors and medical imaging; its performance, supply constraints and manufacturing costs can directly affect revenue and margins for companies that make or use optical and sensing devices.

photodiode technical

"indium gallium arsenide (InGaAs) photodiode technology for consumer sensing"

A photodiode is a small electronic component that converts light into an electrical signal, like a tiny solar cell or light meter. Investors care because photodiodes are key parts in devices that detect or measure light—from fiber-optic communications and medical sensors to cameras and autonomous vehicle systems—so demand, cost, and supply constraints can directly affect a company’s products, revenue and competitive position.
