Brand: Lake Shore | Category: Nanotechnology

The Model 121 is a programmable DC current source that supplies precise, low-noise and highly stable current up to 100 mA. It is used to excite resistance temperature sensors and other low-power devices where a settable, well-regulated current is needed.
| Parameter | Value |
|---|---|
| Programmable current output | 100 nA–100 mA |
| Preset output levels | 13 |
| Display | 3-digit LED |
| Computer interface | USB |

Alongside their standard range, Lake Shore design cryogenic probe stations to suit a specific experiment. The published examples are a cryogen-free superconducting magnet station, custom liquid helium and liquid nitrogen cooled stations, a room temperature vacuum station and a miniature transportable vacuum chamber. Each example carries its own field, temperature, sample size and vibration figures, and the miniature chamber is stated to need no gate valves.
This insert carries van der Pauw and Hall bar samples inside a PPMS cryostat, with a fully guarded signal path from instrument to sample. Used with the M91 FastHall controller it measures resistance from 10 milliohms to 200 gigaohms between 1.9 K and 400 K. An integrated Cernox sensor reads sample temperature.
The PS-HM-8425 package adds Hall measurement to Lake Shore's CRX-VF cryogenic probe station. It supports DC Hall measurements on wafer-scale materials and structures as a function of temperature and field, and is supplied with a switch matrix, current source, voltmeter and a PC running the 8400 Series HMS software. Van der Pauw, Hall bar and gated Hall bar measurements are all covered, with optional modules for extra probe arms, high resistance work, gate bias voltage and QMSA software.
