2.3 C-V graph
The measured MOS capacitance (called gate capacitance) varies with the applied gate voltage.
① Measurement of C-V characteristics
-Apply any DC bias, and superimpose a small (15 mV) ac signal
-Generally measured at 1 MHz (high frequency) or at variable frequencies between 1KHz to 1 MHz
-The dc bias VG is slowly varied to get quasi-continuous C-V characteristics
② C-V chara
2.7 Shrinkage
- Theoretical value: (a=35, : Maximum Shrinkage Strain Ratio)
- The process of finding 'a'
1. Arranging excel data
2. Finding 'a' with using a grapher program
(Converting Excel data into graph shape)

(Finding 'a' with using shrinkage equation)
3. Finding 'a'
Sample illumination is transmitted white light and contrast in the sample is caused by absorbance of some of the transmitted light in dense areas of the sample.
2) Dark field microscopy
Dark field microscopy describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen is generally dark.

return by the time the last petal fell, then the spell would
be broken. If not, he would be doomed to remain a beast for
all time. As the years passed, he fell into despair, and lost

Why?
PILOT
Good weather. It wont hold though.
Theres a cyclone forming up in the
Admiralties, should swing down this way
in a few days.
NORMAN
What happens then?
PILOT
Everybody just clears the hell out.
Weather can be really tough in this part
of the world. I was stationed in Florida
and Ive seen a lot of hurricanes, but
youve never seen anything like a Pacific
cyclone, si
