In a low-energy transmission electron microscope (TEM), the typical average beam current is about -1.00 mu A. If a material sample is exposed to this electron current for 17.8 min, how many electrons impact the material during that time? electrons

Answer the following questions (just give answer, no complex equations please): To measure the dispersive of phonon, we used neutron inelastic scattering method. Please tell me why a traditional Raman scatting facility which is able to measure the phonon energy cannot do it? To measure the effective mass of a hole or electron in a material, usually we have to go to low temperature. Why is that? If I have one solid, I heat it up; the lattice constant increased...

Problem 2 (20 pts) A scanning tunneling microscope employs a small sharp conducting tip that is brought into close proximity of a material, as TIP shown in the figure at right. The vacuum region between the tip and the sample acts as a potential barrier because the electrons in the material have a lower potential than in free space (work functions of the materials). Therefore, the current across the vacuum is proportional to the transmission probability T approximated by a...

To gain an appreciation of the water consumption needs for a modest city such as Gainesville, we will consider converting UF's football stadium or the O'Connell Center into a water reservoir. Each group should divide into two teams (sub-group A and B), with each sub-group answering the following questions in a short report to be posted on Canvas by one of the Co-...

This is a challenging multi-step problem. Solve it on paper, writing out each step carefully. When doing calculations, do not round intermediate values. Note: If you have approached the problem in a principled way, do not abandon your approach if your numerical answer is not accepted; check your calculations! The Bohr model correctly predicts the main energy levels not only for atomic hydrogen but also for other "one-electron" atoms where all but one of the atomic electrons has been removed,...
