(a) How many silicon atoms are there in each unit cell? (b) How many silicon atoms are there in one cubic centimeter? (c) Knowing that the length of a side of the unit cell (the silicon lattice constant) is 5.43 Å, Si atomic weight is 28.1, and the Avogdaro's number is 6.02 × 10²3 atoms/mole, find the silicon density in g/cm³.
In the Taylor Expansion, it looks like they've made x_0 = x_1, x_2 and made x = x_1 - a, x_2 - a. I don't understand how they can use that substitution for x_0 since it is a constant, and x_1 and x_2 are variables that can change.
2) In one of the most recent silicon industry achievements of 2021, a single transistor takes up a rectangular area on a microchip that measures 10[nm] by 2O[nm]. The early microchips in the 1970's had rectangular transistors that each measured approximátely 20[um] by 40[µm]. How manv of the new 2021 transistors could fit inside the same area of a single 1970 transistor? A) 400 B) 4000 C) 40,000 D) 400,000 É 4,000,000
Grüneisen parameter for silicon The silicon crystal (diamond structure) has the following properties at 500 K. The lattice parameter (a) = 0.5440 nm, thermal expansion coefficient (a) = 3.6x106 K-', and the bulk modulus is about the same as that at room temperature (K = 99 GPa). The Debye temperature of Si is 625 K. At room temperature (300 K) its density is 2.33 g cm³, and its lattice constant is 0.5430 nm. Calculate the Grüneisen parameter at 500 K and compare with its value at room temperature in Table 1. Is 3 constant?
