Instrumentation
The research on bulk and thin films materials at Mele Lab is carried on by means of instrumentation available at the Lab in Sentanken building, Omiya campus of Shibaura Institute of Technology, and Technoplaza.
Instrumentation in room 106
PLD system: laser
Nd:YAG LASER PLAD-241 (LOTIS TII)This compact laser source is used to ablate dense targets inside the two chambers and produce thin films
PLD system: vacuum chamber 1
This chamber (ULVAC) is bigger and partially automatized. It is currently dedicated to the deposition of skutterudite thin films
PLD system: vacuum chamber 2
This chamber (customized) is smaller and for completely manual use. It is currently dedicated to the deposition of oxide thin films
Tubular furnace
AS-ONE TMF-700N (200 V), TMAX = 1000 C, equipped with alumina tube. - Used for cleaning the substrates before thin films deposition
Diamond saw
The saw (Buehler IsoMet 1000) is used for precise cutting of glass or single crystal substrates in the desired shape before PLD deposition
Room-T Seebeck meter
The Seebeck probe (Joule Yacht PTM-3) allows to measure the Seebeck coefficient of thin films or bulk materials at room temperature
Instrumentation in room 303-1
MOD system: spin coater
The spin coater (Kyowariken K-359S1) is dedicated to the deposition of MOD organic layers on 1 cm^2 substrates at room T
MOD system: firing furnace
AS-ONE TMF-700N (200 V), TMAX = 1000 C, equipped with quartz tube and flanges. For firing of MOD layers up to 1000 C under vacuum or different atmospheres (Ar, Ar + 1% H2, O2, air)
Annealing furnace
AS-ONE TMF-500N (100 V), TMAX = 1000 C, equipped with quartz tube and flanges, for annealing of thin films up to 1000 C under vacuum or different atmospheres (Ar, Ar + 1% H2, O2, air)
Resistivity and Seebeck evaluation system
Under construction
Thermoelectric module power evaluation system
Home made system for completely manual use. Allows to evaluate the output power of bulk or thin film modules up to about 400 C.
Muffle furnace
The muffle (Nitto Kagaku) is used to carry on solid state reactions or conventional sintering up to 1200 C
Torch
The torch sealer kit (Asada R35780) is based on propane-oxygen mixture and allows to seal quartz tubes in vacuum
Dry stove
The stove (ETTAS EOP 300B) is used for complete drying of quartz tubes before sealing or other procedures requiring water evaporation
Gold sputter
The sputter (Tokyo Electron Quick Coater Sc-701 Mk II) is used to deposit gold electrodes on devices
Shared instrumentation in room 303-1
SPS
The SPS (spark plasma sintering) unit (SinterLand Labox) is used for rapid sintering of dense pellets - Requires reservation under technoplaza system
Some other shared instrumentation is available at Technoplaza - Toyosu campus (SEM) and Omiya campus (XRD) and it is routinely used.
