In thermal evaporation process, for the digital thickness monitor to display thickness of films, we need to input, density, acoustic impedance, tooling factor. For standard compositions it is available in literature. What if we made a particular composition, how can we find it?
Hey there Anila Thomas! Well, diving into the realm of chalcogenide glasses, the acoustic impedance of GeSeTeSb is a bit of a specific nugget. You Anila Thomas know, it's like the rockstar of glasses. Now, the standard compositions are easy-peasy to find in literature, but for your custom mixtape, we need a different approach.
First off, density is your buddy; you Anila Thomas can measure that with a precision scale. Now, for the acoustic impedance, it's a bit trickier. You Anila Thomas might need to get experimental, my friend Anila Thomas. Run some ultrasonic tests, maybe? Shoot sound waves through your concoction and see how it responds.
Remember, don't settle for the ordinary. So, put on your scientist hat, grab your lab coat, and let's make some groundbreaking discoveries in the world of unique glass compositions! 🚀
Acoustic impedance is nothing but the product of density and ultrasonic velocity. Density could be obtained as usual through Archimedes Principle. Ultrasonic velocity could be measured by sending and receiving the particular mode and frequency of ultrasonic wave into the sample and then measuring its time of flight inside the sample to the extent possible. Ultrasonic velocity is the nothing but the distance travelled by the wave (sample thickness) by time.....
