Small-field d.c. conduction inn-type germanium in the presence of large microwave field is theoretically studied assuming a Maxwellian distribution function for the carriers.Scattering by intra-valley acoustic and optical phonons and by equivalent inter-valley phonons have been taken into account, but the effect of non-equivalent inter-valley scattering has been neglected.

Nanotechnology is the study, application, and engineering of materials, devices and systems on a very small scale: by definition, it involves the manipulation of matter with at least one dimension sized from 1 to 100 nanometers, deemed nanomaterials. At this scale, sometimes referred to as the quantum realm, quantum mechanical effects play a ...

Highly uniform silicon/germanium nanoparticles can be formed into stable dispersions with a desirable small secondary particle size. The silicon/germanium particles can be surface modified to form the dispersions. The silicon/germanium nanoparticles can be doped to change the particle properties. The dispersions can be printed as an ink for appropriate applications.

High chemical yields, up to 73%, were achieved for germanium (Ge) nanocrystals synthesized in solution with germanium diiodide (GeI2) and LiAlH4 as a reducing agent in tri-n-octylphosphine (TOP) or tri-n-butylphosphine (TBP). Ge nanocrystals were characterized by transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), …

But why Germanium? Because Ge has the smallest band gap of the semiconductors. An incident particle will lift more electrons out of the ground state and put them into the conduction state. The signal reaching the preamp is larger with Ge than any other semiconductor. Germanium is the gold standard for the detection of gamma rays.
