| Calculate the dispersion relation and density of states (including partial DoS) for at least one material of your choice (except Si), using the Wien 2k software. Demonstrate your creativity by one expansion of this basic assignment to achieve the highest possible grade. | 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. |

| Write a **paper** that describes your findings. It should state what you are trying to investigate and include some 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. | Write a **paper** that describes your findings.

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. |

| Summarize your results as a **poster** for the group to be shown in the hour reserved for MT2. This is a conference of your peers, and may also be attended by interested parties such as former and prospective PH 575 students, and faculty. | Summarize your results as a **poster** for the group to be shown in the hour reserved for MT2. This is a conference of your peers, and may also be attended by interested parties such as former and prospective PH 575 students, and faculty. You should not go to great expense to generate the posters; 8.5” by 11” sheets pasted to thin poster board will be fine. The total size is limited to about half the size of a whiteboard in WGR 304. Text and diagrams should explain your calculations, and provide supplementary information about your material. In the poster session, half the class will remain with the poster for the first half while the other half circulate; roles are swapped for the second half. |

| 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.
