Energy storage requires germanium

What materials can be used to build quantum information-processing devices in germanium?

Three materials platforms have emerged as strong contenders in the race to build quantum information-processing devices in germanium: Ge/Si core/shell nanowires (NWs), Ge hut wires (HWs) and Ge/SiGe planar heterostructures. Each of these platforms offers specific advantages but also poses challenges, as we shall discuss.

Can germanium be used to develop disruptive quantum technologies?

In the effort to develop disruptive quantum technologies, germanium is emerging as a versatile material to realize devices capable of encoding, processing and transmitting quantum information.

Is germanium a good anode material for lithium ion batteries?

Germanium (Ge) is a promising anode material for lithium ion batteries due to its high theoretical capacity. However, its poor cycling stability associated with its large volume changes during discharging and charging processes are urgent problems to solve. This provides opportunities to engineer materials to overcome these issues.

Should lithium ion batteries be replaced with silicon or germanium?

Lithium ion batteries with significantly higher energy and power density desired for new personal electronic devices, electric vehicles, and large-scale energy storage, require new materials. This review focuses on the replacement of the graphite anode with silicon or germanium.

Can germanium be used as a hybrid s–SM device?

Most experimental research has been focusing on hybrid S–Sm systems involving small-band-gap III–V semiconductors such as InAs and InSb. Germanium is an appealing alternative semiconductor to host hybrid S–Sm devices and enable their large-scale integration on Si.

Are thiol- and alkene-passivated germanium nanowires suitable for high capacity Li-ion batteries?

Corrosion resistance of thiol- and alkene-passivated germanium nanowires Tin-seeded silicon nanowires for high capacity Li-ion batteries Stable, high capacity cycling (1800 mA h g −1) of Si anodes for more than 100 cycles was demonstrated.
