Uh, Thanks your reply first!
A homogeneous model is a second choice, but it's okay. I want to place a embedded inductor in the SAM head
phantom to receive the outer signal. And the specific absorption rate in the tissue is of my concern. I need to measure
the SAR value.
Have you do some similar...
Hello, everyone!
I am studying the specific absorption ratio(SAR) in the head from wireless devices. So, I need
a human head model, namely a phantom to simulate the realistic situation.
I have found a free head model on the web: https://noodle.med.yale.edu/zubal/data.htm.
But I don't know...
hello, are you still here?
I have encountered the same problem when i simulate a transformer, which says it could not preserve critical nodes. Had you solved the problem?
Hope for your reply!
1. I agree with your saying-- “Could be that undoped, vs
the implant-and-activation thermal processing and/or
epi growth applies a very different thermal stress/strain.
Or, who knows”. It's indeed that we can hardly estimate
the influence of fabrication parameters eg. doping temperature...
The first time I broke one wafer is when I washed it
using deionized water, which may be explained
by too much mechanical stress.
The second situation drove me to consider why the high resistivity-wafer
broke again. 7 wafers were placed in a box. And I droped it on the floor uncarefully.
The...
Thank you for your reply at first!
1. I have two kinds of Boron-doped p-type 4-inch silicon wafer:
A:high-resistivity 1500ohm·cm(light doped);
B: low-resistivity 10ohm·cm(heavily doped). I found high-resistivity wafer is more likely to be broken.
You said "even near-degenerate doping...
Recently, I'm intrested in the strength of doped Si wafer. Because I have found that light doped Si wafer is more likely going to broke in experiment.
I dont know the exact reason, but i want to find it out. Does anybody has some ideas?
I want to download an article which discuss this problem...
can anyone help me?pls.
