Cheng Lab: Facilities
Laboratory and fabrication equipment:
The Cheng Lab has a 925-square-foot laboratory space divided into three rooms provided by ½ñÈÕ³Ô¹Ï.
The two adjacent bigger rooms are designed for miro- and nanofabrication use, suitable for photolithography and film deposition:
- a 100-square-foot class 1000 soft curtain cleanroom with purify water system and the ceiling lighting suitable for photolithography
- AJA ATC Orion 5-source Sputtering Deposition System
- Karl Suss MJB 3 Mask Aligner
- Filmetrics thin film measurement system
- three chemical hoods with in-house vacuum, compressed air and gas lines
- the ultrasound cleaner and programmable hotplate for photolithography procedure
- TMC vibration isolated optical table
- ETS humidity control chamber
- Princeton Applied Research potentiostat (VersaSTAT-200) for template electrochemical deposition
The third room provides a quiet space for computer simulation and data analysis.
Computers:
- Two workstations with the Mumax and OOMMF software packages, Mathematica and MatLab software installed for micromagnetic simulation is located in the computer room.
- Several networked computers with appropriate instrument control and data analysis software are available in the nanofabricaiton rooms.
Characterization equipment:
The Cheng group shares or has free access to the following on-campus major instruments:
- PMS MicroMagTM3900 VSM magnetometer
- Agilent 5500 scanning probe microscope with atomic force microscopy and scanning tunneling microscopy capabilities
- Rigaku Ultima IV X-ray diffraction (XRD)
The Cheng group has free access through general user proposals to the following DOE user facilities:
- X-ray magnet circular dichroism spectroscopy and x-ray PEEM imaging at the Advanced Light Source of Lawrence Berkeley National Laboratory
- X-ray magnet circular dichroism spectroscopy at the Advanced Photon Source of Argonne National Laboratory
