FAQS 4

How to grow a 3-inch diameter Ge crystal?

Important basic process steps for the very high purity, 3-inch diameter Ge crystal growth technology development were successfully established in-house and are presented in detail. Crystals with a diameter of 80 mm and a length of up to 140 mm length could be grown. First, the GeO 2 source powder has to be reduced to Ge metal by hydrogen.

What is the EPD value of a Ge crystal?

An ultrahigh-pure Ge crystal with EPD values of 4620 cm −2 (top part: sample A); 8380 cm −2 (after shoulder part: sample B), and 17,000 cm −2 (bottom part: sample C). Table 2. Hall-effect measurements (77 K) showing ultrahigh purity of the crystal

What purity is required for a Ge crystal?

But for a normal semiconductor grade Ge crystal, a starting material purity with an electronic grade (6 N) would be required. The intrinsic resistivity of Ge is about 50 Ω cm at room temperature and generally corresponds to a chemical purity of 6 N or better. The ZR was performed under pure H 2 atmosphere supplied from a Pd diffusion cell.

Can n-type or p-type Ge crystals be produced with high purity?

But, if the concentrations of the shallow donor or acceptors in the starting material for the growth can be controlled and maintained, an undoped n-type or p-type Ge crystals with very high purity can be realized.
