The base semiconducting material used in virtually all of our The base semiconducting material used in virtually all of our modern integrated circuits is silicon. However, silicon has some limitations and restrictions. Write an essay comparing the properties and applications (and/or potential applications) of silicon and gallium arsenide.
The outer surface of a steel gear is to be The outer surface of a steel gear is to be hardened by increasing its carbon content. The carbon is to be supplied from an external carbon-rich atmosphere, which is maintained at an elevated temperature. A diffusion heat treatment at 850(C (1123 K) for 10 min […]

For some viscoelastic polymers that are For some viscoelastic polymers that are subjected to stress relaxation tests, the stress decays with time according to where s(t) and s(0) represent the time-dependent and initial (i.e., time = 0) stresses, respectively, and t and t denote elapsed time and the relaxation time; t is a time-independent constant […]
Gold forms a substitutional solid solution with silver Gold forms a substitutional solid solution with silver. Compute the number of gold atoms per cubic centimeter for a silver-gold alloy that contains 10 wt% Au and 90 wt% Ag. The densities of pure gold and silver are 19.32 and 10.49 g/cm3, respectively.
Given here are the solidus and liquidus temperatures for the Given here are the solidus and liquidus temperatures for the germanium-silicon system. Construct the phase diagram for this system and label eachregion.
Gallium arsenide (GaAs) and gallium phosphide (GaP) are compound Gallium arsenide (GaAs) and gallium phosphide (GaP) are compound semiconductors that have room-temperature band gap energies of 1.42 and 2.25 eV, respectively, and form solid solutions in all proportions. Furthermore, the band gap of the alloy increases approximately linearly with GaP additions (in mol%). Alloys of […]
