Zz, I wish you were my advisor :)

Regarding getting external awards/fellowships... it's good to have "connections"

That's how we do. Builds character.

Depends no your adviser and also what you want to do after graduation. Obtaining your own funding is, for example, essential for small startups. Do you want to start your own company? Also, writing grants and applying for $$ is essential as a professor. Do you want to be a prof when you...

Or.. the advisor can push students to get their own graduate funding since it builds character, thus bringing me back to my original question. I am a senior grad student so I've been through most of the "early years" to be eligible for NSF, DOE, DOD

True, but we are all encouraged to get our own funding. This would be for physics, but more specifically solid state physics with broad applications in medical diagnosis, environmental monitoring and continuing the information revolution.

Hello all, Would anyone know of a website that has a comprehensive list of fellowships, grants and funding opportunities for graduate students in the sciences? I know of the big ones like NSF, DOE, NDSEG, etc but was wondering if there are smaller grants for research or stipend that is available?

I'm interested in calculating the resistance of an object using the formula: R=ρ (L/(T*W)) where L is the length and T*W is the cross sectional area. My object is however, a wedge, so I do not know exactly how to calculate the resistance without doing an integral...

Also, resistivity does change with with the shape of the material, for example look in: A. Naeemi et al., Proc. IEEE Int. Interconnect Technol. Conf., 183–185 (2008). Especially in sub-10nm scales, there can be width-dependent resistivity. Thinking out loud to a response for my...

Some follow up questions: 1. What if the resistance was known for, say, material A in series with material B, but both resistivities are unknown. Is there a way to extract the resistivity of material A? 2. What if we knew the resistivity of material A, but not of material B? Knowing the...

Hello All, I was curious to know if there is a way to calculate resistivity of a wire that did not have a uniform cross section? For example, what if the cable was in a bow-tie geometry? Is there anyway to quantify the electrical resistivity of the constriction (the area of the cable that has...

does my question make sense?

Not devices, just a metal connected by source drain electrodes, for example. Take a 1um diameter copper wire and sweep the potential from 0V to 3V. Will the current have a linear dependence on voltage? What about a semiconductor? For example, theory wise, the dependence of current on...

Hello, Is there a well known theory on how metals and semiconductors should behave, electrically, while under a high voltage bias? Say, 2-3V? For example, how does the conductivity change as a function of voltage bias as we go from the low bias regime into high bias? Is there a linear...

Say I have a function: f(x,y) I have values for f and y such that I can make a plot of f vs y... however, from the values of f and y, I am interested in finding what x is. The x value should be a constant that is optimized to fit the f vs y graph. Is there a way I can do this in...
