Question

Please help with all parts, thank you!!

(i) Thermal distortions and vibrations do not perturb smaller devices as much as large ones
because
(a) the resonant vibrations of a system are inversely proportional to its mass
(b) the resonant vibrations of a system are directly proportional to its mass
(c) smaller things tend to need less energy in order to function
(d) none of the above
(ii) Formation of cylindrical nanowires and nanodots are examples of the progressive generation
of curvilinear nanostructures from macroscopic bulk material via
(a) reduction in dimensions along one direction and two directions, respectively
(b) reduction in dimensions along two directions and three directions , respectively
(c) reduction in dimensions along all three directions
(d) non of the above
(iii) (a) True or false: When numerous atoms are brought into close proximity, only the
The highest occupied energy sublevel forms a band.
(b) True or false: Quantum confinement relates only to those electrons that would
otherwise be mobile-the conduction electrons.
(c) What name is given to the distance separating an electron-hole pair in a
semiconductor?
(d) True or false: The band gap of a quantum dot is directly proportional to its size.
(e) Name the structures in which partial confinement is achieved.
(iv) The chemical potential (u) of smaller size clusters is bigger than that of bigger size clusters
because of
(a) their small size
(b) the fewer number of atoms in them
(c) surface area is smaller
(d) their surface is more curved

Good morning interns, This is Ms. Gorman from the sales department. We have just secured a new, multi-million-dollar account! We are so good here in the sales department of Heavy-Duty Box Inc. The manufacturing director, Mr. Tsosie, has instructed me to send this problem out to all of you as this will be a deciding factor in which of you get offered the full-time positions available at the end of the internship! Our new client, Beastie Bearings Inc., needs the heaviest duty box we make here at Heavy-Duty Box for their bearings. The following email from Ms. Venegas from Beastie Bearings provides the information you will need. Remember, our mark-up sales price is 150% of what it costs us to manufacture the product. The cheaper it is for us to produce the box, the lower the cost for our client. There is also a grading rubric attached that Mr. Tsosie will be utilizing in evaluating your work. I would advise you to follow it well if you want a position! Good luck interns, Ms. Frances…
