semiconductorwafers: Ge wafer

-
We have applied quinhydrone/methanol (Q/M) treatment to germanium (Ge) surfaces and shown that this treatment is also effective for passivating Ge surfaces for minority carrier lifetime measurements. Surface recombination velocity (S) of less than 20 cm/s has been obtained, which enables us to accurately evaluate the bulk lifetime of minority carriers, τb, in Ge wafer. To the best of our knowledge, this is the first report on wet chemical treatment successfully applied to Ge surfaces achieving low values of S.

The sunshine time is longer in summer, the sunlight penetrates the glass directly in the room. One part of the thermal radiation can be absorbed or reflected by the glass, the other part is released through the glass in the room and increase the indoor temperature constantly. It is very important to do a good shading for aluminum windows and doors . 1.Shading with curtains Choose the curtain of shading fabric, match again with shading cloth, also can have very good shading effect.
