Laser Scribing System
In a scribing configuration, the system can isolate individual cells on a research
scale device or perform the scribes necessary to integrate a module. High peak power
lasers with wavelengths of 1064 nm, 532 nm, and 355 nm, which add flexibility to the
system, are available. A tightly focused beam creates a small scribe width, approximately
40 µm, resulting in a larger active cell area then manual scribing, increasing the
output power of the cell as well as decreasing the wasted materials. TOP OF PAGE
Ultrasonic Cleaners and Deionized Water System
There a several Ultrasonic Cleaners housed within PVIC. The cleaners deploy ultrasound
between 20-400 kHz to thoroughly clean laboratory substrates or superstrates, vacuum
parts, and other delicate items. These systems coupled with the deionized water system
in enables for contaminant free substrates or superstrates as long as the appropriate
surfactant is used. TOP OF PAGE
Fume hoods
The fume hoods allows for localized ventilation to limit exposure to hazardous or
toxic fumes, vapors, or dusts. There is at least one fume hood in each of the main
labs with 4 in each of the wet chemistry labs. They work by air being drawn in from
the front of the cabinet and then expelled outside of the building for the ducted
hoods or through filtration for the recirculating hoods. TOP OF PAGE
Cleanrooms
The cleanrooms have a controlled level of contamination to have a low level of environmental
pollutants. These pollutants can be dust, airborne microbes, aerosol particles and
chemical vapors. TOP OF PAGE
Analytical Ovens
The analytical ovens are able to provide uniform temperatures throughout the whole
oven. There a various sizes and types house at PVIC. And can be use for applications
like annealing, curing, drying, polyimide baking, sterilizing, and other uses. TOP OF PAGE
Tube Furnace
The tube furnace consists of a fused quartz reaction tube surrounded by heating coils
in a thermally insulating matrix. This furnace allows for samples to be heating in
a controlled environment. The current set-up allows for N2, Ar, and dry air. TOP OF PAGE
Carbon Nanotube Synthesis System
Carbon single-walled nanotubes (SWNTs) are a one dimensional material with extraordinary
properties that could be advantageous in a wide variety of applications. UT has established
laser synthesis capabilities and the associated purification processes. The UT synthesis
system is versatile enough to produce a wide range of diameter tubes by manipulating
the synthesis parameters. TOP OF PAGE
Coy Laboratories Anaerobic Chamber
The Coy anaerobic chamber is a high humidity, oxygen free chamber. The oxygen is removed
by a catalyst that uses hydrogen to produce water. Feed throughs allow a number of
measurements to be performed in the chamber. This system is ideal for oxygen sensitive
experiments that require the use of water. TOP OF PAGE
Glove boxes
The systems utilized here, from MBraun Inc., feature a re-circulating purifier to
continuously remove oxygen, water, and solvent vapors from the atmosphere. New materials
research often involves materials which are not stable for long periods of time. To
extend sample lifetime, they are stored in an inert nitrogen atmosphere where Oxygen
and water contents are kept at less than 10 parts per million. TOP OF PAGE
Analytical Balances and Microbalance
There are several analytical balances in PVIC. They are accurate to 3 and 4 significant
figures or 0.1 and 0.01 mg. All of the analytical balances have a transparent enclosure
with doors to prevent dust and air current from affecting the operation. There is a microbalance that is capable of making precise measurement in the microgram range. TOP OF PAGE
Karl Suss MJB3 Mask Aligner
The mask aligner is used in lithographic patterning and is configured for use with
3” wafers. TOP OF PAGE
