Keysight 5100 AFM (aka Leia)

Keysight 5100 AFM comprises a scanner of 60 x 60 microns in X / Y and 6 microns in the Z axis. The equipment can use a special liquid cell and controlled environment chamber for conducting scanners at low humidity or in nitrogen. The maximum sample size is 3x3 cm in X / Y and 2 cm thick. The equipment works in the Constant Amplitude Dynamic mode for obtaining topographic images, however Contact mode is also a possibility. The equipment uses an external generator module that can apply in-plane magnetic fields upto + -800 Oe. The equipment is specifically employed to acquired topographic images, having a low noise architecture that allow the acquisition of 500 nm size images.

SPM2: Keysight 5500 LS AFM (aka Darth Vader)

Keysight 5500 LS, it has a 90x90 microns in X / Y and 15 microns in the Z axis closed loop scanner. The SPM is equipped with three independent Lock-in amplifiers that can be fully configured through the use of an external Signal Access Box. The equipment can be used with the following modes: Piezoresponse Force Microscopy, Electrostatic Force Microscopy, Kelvin Probe Force Microscopy, Scanning thermal Microscopy (from 2Q2016), Current Sensing Atomic Force Microscopy, PhotoConductive Atomic Force Microscopy, Bimodal Atomic Force Microscopy. It also has Closed Loop capability that significantly improves the positioning in X and Y as well as a motorized stage, with accuracy of + -3 microns, and a range of + -15cm in X / Y and 3cm in Z axis, so sample size may reach up to 25 x 25 cm and 3 cm thick. A Q-Control is also available to enhance images in liquid. It has a separate accessory for measuring humidity and temperature inside SPM box. A sample cooler and heater with a range of -60ºC to 90ºC and a separate heater up to 350ºC can be used in this equipment. A special current-to-voltage amplifier "Resiscope II" from CSI instruments can be used to acquire topography images. A separate accessory for illuminating samples in the Visible and UV spectra is also available.

SPM3: Keysight 5500 AFM (aka Luke)

Keysight 5500, it has a 90x90 microns in X / Y and 15 microns in the Z axis closed loop scanner. The SPM is equipped with three independent Lock-in amplifiers that can be fully configured through the use of an external Signal Access Box. The equipment can be used with the following modes: Piezoresponse Force Microscopy, Bimodal Atomic Force Microscopy and Dynamic Topography. It also has aClosed Loop capability that significantly improves the positioning in X and Y. Sample size is limited to 3 x 3 cm in the X and Y directions and 1 cm in the Z direction. A Q-Control is also available to enhance images in liquid. It has a separate accessory for measuring humidity and temperature inside SPM box. A separate heater up to 350ºC can be used in this equipment.

SPM4: Nanotech Cervantes (aka Jabba)

Nanotec Cervantes FullMode SPM System is a modular, open and versatile microscope, designed not only for obtaining the highest quality images, but also for those applications that require a characterization of other physical properties of your sample. Currently we use this equipment for topography, and as a separate equipment for nano positioning systems.
