Uniform phosphorus doping of untapered germanium nanowires

Oct 31, 2021We actually expect n to be lower than because phosphorus is the only dopant specie introduced in the nanowires. This estimation of μ gives therefore a lower bound for the electron mobility in our material. The known value for bulk germanium doped at 6.6 10 18 cm −3 is 476 cm 2

Germanium

Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbors silicon and tin.Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature.

Abundance of elements in Earth's crust

The abundance of elements in Earth's crust is shown in tabulated form with the estimated crustal abundance for each chemical element shown as mg/kg, or parts per million (ppm) by mass (10,000 ppm = 1%).. Estimates of elemental abundance are difficult because (a) the composition of the upper and lower crust are quite different, and (b) the composition of the continental crust can vary

point of the gold–germanium alloy decreases with the dia-meter of the nanowires [18–21]. Alternatively, hydrogen chloride (HCl) can be employed to grow untapered nanowires of bigger diameter, as demonstrated on silicon [22, 23] as well as germanium [24].

Element reactions. This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of phosphorus. For each compound, a formal oxidation number for phosphorus is given, but the usefulness of this number is limited for p -block elements in particular.

Doped Germanium

The Ge(1) and Ge(2) have been identified as trapped-electron centres. 28 The characteristic absorption of Ge(1) and Ge(2) are 280 nm and 213 nm. The GeE′, previously known as the Ge(0) and Ge(3) centres, which is common in oxygen-deficient germania, is a hole trapped next to a germanium at an oxygen vacancy, 29 and has been shown to be independent of the number of next-neighbour Ge sites.

The disclosure relates to yellow karat gold metal alloys particularly suited for the casting of jewelry articles such as rings, bracelets, earrings, and the like. The alloys include varying amounts of germanium up to about one percent by weight of the total volume of the alloy which serves as an oxygen scavenger, and which may be recycled along with scrap alloy material after casting.

Germanium

N-type materials are intrinsic 3-D crystals of silicon or germanium subjected to controlled impurification with chemical elements from the V-a column of the periodic table (e.g. arsenic or phosphorous), behaving as a semiconductor because of the availability of unbound electrons belonging to

Doped Germanium

Huang et al. investigated a SPR waveguide immunosensor designed by germanium-doped silicon dioxide (213). The sensor consisted of a 10-μm SiO 2 substrate layer (n = 1.469), a 10-μm Ge–SiO 2 channel guide (n = 1.492), and a 50-nm gold film layer for immobilization of biomolecules and SPR signal detection (see Figure 7).
