On the bottom right-hand side of the third page of the pdf attached (page 2 of the article), the author states:
"Metal deposition rates are easily converted into the oxide growth rate under the assumption that the metal arrival rates are the rate limiting steps, which is true for growth under oxygen- rich conditions."
I am having trouble understanding this, so please answer the following questions to clarify it for me.
(a) What is meant by metal arrival rates being "rate limiting steps?" (Does this refer to oxidation?)
(b) Why is this true? (Why are metal arrival rates rate limiting steps?)
(c) What exactly is meant by an "oxygen-rich environment?" I haven't seen a technical definition of an "oxygen-rich environment" anywhere in the literature.© BrainMass Inc. brainmass.com October 25, 2018, 7:32 am ad1c9bdddf
Look at figure 1 of the pdf article you attached.
a) The metal is deposited on the substrate from two sources - effusion cells and electron beam evaporator. The rate at which this deposition takes place is the metal arrival rate on the substrate.
b) This will be the rate limiting step if the environment is oxygen-rich. There are two processes taking place i.e. 2 steps. One is the metal deposition on the substrate and the other is the reaction between the metal and oxygen. An oxygen-rich ...
The rate limiting steps in metal oxide epitaxy is examined in the solution. What is meant by metal arrival rates being "rate limiting steps" is examined.
Long Term Financing, Capital Stucture, Risk Management w/Acquisition Analysis
The calculations are difficult and I need help determining what formulas to use and what interpretation guidelines should be. The problem is vague so I am a little lost since it doesn't offer exact criteria. What I need is guidance through the problem and nudges in the right direction.
1: Report on Applied Materials long-term financing policy & capital structure.
a. Identify the firm's most recent long-term financing decision (e.g., debt, IPO, seasoned equity offering, secondary offering). Analyze the economic, business, and competitive background in which the financing occurred, and identify cost and risk trade-offs.
c. Discuss what changes you think would occur to your finance policy and capital structure if your firm was forced to consider re-organization and bankruptcy strategies.
d. Assume that your firm will be investing in the global market. What international investment and financing opportunities would you consider - and why? Also, discuss foreign exchange risk and give an example that analyzes how foreign exchange rates could cause a loss to the firm
