| One of the goals of the course is to become familiar with modern computational software that allows one to solve difficult problems. You will use the software package Wien 2k to calculate the band structure of a semiconductor, metal, or insulator. Decide on an interesting system (talk to me and others about what is feasible). You always start by reproducing the work of others, and then go on to explore by yourself. More information about the program is under the Wien 2k link. You will calculate (at minimum for a passing grade) the dispersion relation and the total and partial densities of states of an interesting material. You will also calculate at least one other property using the Wien 2k advanced options – electron density, optical properties etc., for a B or higher grade. The difficulty of the project will be taken into account in assigning the grade. | One of the goals of the course is to become familiar with modern computational software that allows one to solve difficult problems.

| Write a **paper** that describes your findings. It should state what you are trying to investigate and include motivation for the choice of material. This paper should distill the knowledge you have gained about electronic structure, and be well-constructed to be very helpful to an incoming PH575 student. It will show evidence of your scientific curiosity, and your ability to explain the essential concepts. It should should explain (i) what you have learned about band structure calculations during this process, and (ii) explain what is topical and interesting about your material in somewhat greater detail than you poster. Include references about both sub-parts. | Write a **paper** that describes your findings. It should state what you are trying to investigate and include motivation for the choice of material.

| You are writing a scientific article for an audience of your peers, say incoming PH575 students. You and your peers are highly educated, technically savvy people, but you do not know everything about every material that has ever been discovered. You are educating your peers about a particular material that is of scientific interest or technological importance and you want to convey what is interesting or important about that material from the point of view of a scientist. You are all capable of reading and understanding articles in any of the journals on solid state physics or materials. | You are writing a scientific article for an audience of your peers, say incoming PH575 students.

| Don't work together to construct your posters - the temptation to produce the same format is very strong. This is your poster. But critique someone's poster and offer advice if asked. Tell each where to buy poster materials or how to get access to good printing //etc//. | Don't work together to construct your posters - the temptation to produce the same format is very strong.

| Depends somewhat on the choice of topic and how many figures you include. Typical papers in the past have been about 8 pages including figures and references. | Depends somewhat on the choice of topic and how many figures you include.

| Beware of the "true statements" trap. Just because you say true things does not mean a paper is well constructed or a valuable learning tool. You may have gleaned a piece of information from a well-respected paper in a reputable journal, but quoting that authority without integrating the information into the flow and design of your paper is not helpful (looks just like name dropping!). Also, don’t consider the PH575 instructor as a target reader (in the sense that she knows what you have been taught). She may well give the paper (with no name) to a faculty colleague or a senior grad student as a check to see whether that person thinks the paper is well constructed. | Beware of the "true statements" trap.
