Students will submit the pre-lab online through Canvas before the lab as assigned. It should be submitted electronically to Canvas.ДЄ pre-lab assignment is given in the lab procedure for each lab.

A lab write-up for each group is due at the end of the lab session.

Come to the lab prepared! Read the Lab Procedure ahead of time and complete the pre-lab exercises.

You may not repair it correctly, which may result in taking data using broken or uncalibrated equipment.

Report all problems/breakages immediately! Don't try to fix something yourself.

Be considerate of students and lab staff by taking care of the equipment.

Leave the lab exactly how you found it! Other sections use the same rooms and equipment.

Please obey the following guidelines for each lab: Procedures for each lab can be accessed via your Lab Schedule or in the Experiments section. Students will work in assigned groups of 3 students and complete an experiment during each lab meeting. Gain-phase measurement: 10 Hz to 100 Mhz, -107 dBm to +15 dBm, 0.September 13th: PHYS1101 (PHYS101), PHYS 1151 (PHYS151)Д¬heck the Lab Schedule for more details. HP/Agilent 4194A Impedance/Gain-Phase AnalyzerДЇrequency range impedance measurement: 100 Hz to 40 MHz and 10 kHz to 100 MHz, High speed measurements (1 kHz): 95 ms/meas (4-digit display resolution 60 ms/meas (3-digit display resolution.

Results from other material characterization methods may be included in these models and can provide additional information about the material.ДЇrequency range 100 Hz to 20 kHz (801 spots) Typically, impedance spectra are recorded under controlled DC voltage and current conditions.Д«oth for dielectric spectroscopy and impedance spectroscopy, spectra can be further processed by matching nonlinear curve fitting procedures to the measured data. Here the focus is mainly on the properties of material/electrode interfaces.

Impedance measuring instruments are available to measure circuit components such as capacitors and inductors by using dc bias conditions and frequencies similar to those of the intended application. The fluctuations of the local electric fields are measured and provide insight on the dynamics on a molecular scale. The technique is based on the interaction of an external field with the (local) electric dipole moments in the sample. These properties depend on mobility and relaxations, and hence probe the relaxation dynamics in the material. In the Material Physics Lab the following techniques are available for the characterization of high performance and smart materials:Дieelectric spectroscopy yields information about the dielectric properties of a material as a function of frequency. All users must attend a pre-requisite Safety Meeting in order to obtain access to the Material Physics Lab. In special cases the measurements will be done by the staff.

External parties can apply as well for measurement time in the Material Physics Lab (contact the staff for further information). Depending on the technique and the measurement time a fee may be charged. If the technique is deemed suitable, instructions will be provided to the user on the methodologies and good practice in interpreting the results. Potential users of equipment must first contact one of the staff members listed below to discuss the intended use of the equipment. The equipment can be used by accredited AE researchers and students and others working or studying at the TU Delft. Our experimental techniques were selected to determine and quantify the chemical and physical structure of the material and to assist our researchers in establishing the relationship between material structure and material properties. The Material Physics Lab focuses on the characterization of high performance materials (both polymers, metals and ceramics and composites) for aerospace, space and other high tech applications.
