What advantages does 2 by 6 studs have over 2 by 4 studs?
You can get more insulation when using 2x6 studs rather than 2x4 studs
What are dopants?
Dopants are elements added in very tiny quantities to semiconductors as impurities that modify the electrical characteristics of the semiconductor. They fall into two types, depending on the type of current carrier they introduce into the semiconductor: p-type and n-type.The p-type dopant elements are: boron, aluminum, gallium, and indium; because they have only 3 valence electrons (not the 4 that elemental semiconductors do) they leave voids in the valence band that can act as mobile current carriers called "holes", as these "holes" act as moving positive charges a semiconductor so doped is called p-type semiconductor. The n-type dopant elements are: nitrogen, phosphorus, arsenic, and antimony; because they have 5 valence electrons (not the 4 that elemental semiconductors do) they create extra electrons in the conduction band that are mobile current carriers, as these electrons are moving negative charges a semiconductor so doped is called n-type semiconductor.Note: neither p-type semiconductor or n-type semiconductor is electrically charged, any more than a regular conductor is electrically charged. The charge of the mobile current carriers in each case are balanced by the nuclear charge in the atoms.This ability to make materials that conduct electricity using both "holes" and electrons in different parts of the one piece of material allows the creation of electronic components that could never have even been imagined when the only materials known that conducted electricity used only electrons.

What is minority charge carrier?
In semiconductor devices there are two types of charge carriers: electrons and holes. In N-type doped semiconductor the majority charge carriers are electrons and the minority charge carriers are holes. In P-type doped semiconductor the majority charge carriers are holes and the minority charge carriers are electrons.Some kinds of semiconductor devices operate using minority charge carriers in part(s) of their structure. The common bipolar junction transistor is one of these, they are sensitive to a phenomenon called thermal runaway because additional minority carriers are produced as temperature increases. (field effect transistors however operate using only majority carriers and are thus not sensitive to thermal runaway)
Why for making an n-type semiconductor silicon or germanium is doped with only fifteenth group element like phosphorus?
in silicon or germanium, the valence shell contain 4 electrons. in order to attain stability, they need 4 more electrons, so we doping it either with trivalent or pentavalent impurities. if we are doping semiconductor with any of these, we call it as an extrinsic semiconductor if we are using pentavalent impurity such as phosphorous, there will be an extra electron,which will go to conduction band. we know electron has negative charge therefore we call it as n-type semiconductor
Is germanium is a form of semiconductor material?
Yes it is. Some of the earliest semiconductor devices were made using it.

What is a GSi integrated circuit?
It could be an integrated circuit chip made by a company called GSI Technology that is based in Silicon Valley, California.But if you are asking about a GeSi integrated circuit, that could be referring to one that has been fabricated using the elements Germanium and Silicon which have been specially doped to make its semiconductor components.
