The Chair of Micro and Nanosystems pursues – among others - research on the field of carbon nanotube sensors and thermoelectric devices: www.micro.mavt.ethz.ch We are looking for both research areas for prospective
PhD Students for Zero Power Sensors
The objective of the project on carbon nanotube
(CNT) sensors is the integration of CNTs in a ultra low-power sensor
system for environmental monitoring. The research shall focus signal
evaluation, signal processing and noise reduction of suspended
single-walled carbon nanotube (SWNT) field effect transistor devices
that exploit substantial changes in the electronic transport properties
of the carbon nanotube manifested upon exposure to specific chemical
analytes (e.g. NO2). Device fabrication and integration in sensor
arrays, analog circuit design and concepts of multivariate data analysis
are aspects of the research.
The objective of the project on thermoelectric
(TE) devices is the integration of nanostructured TE materials for the
generation of electric power from temperature differences around room
temperature. Starting from conventional concepts of Peltier thermos
couples, the project shall explore the potential of nanostructured
materials w/r to large area integration and reproducible performance
indicators. The combination of ultra low-power CNT sensors and new TE
devices may yield zero power sensor systems, i.e. sensors, which harvest
energy from the environment and do not need batteries or power
supplies.
The research requires working in semiconductor
clean rooms, e.g. in the Binning and Rohrer Nanotechnology Center
(BRNC), a joint cleanroom of ETH Zurich and IBM Research. The PhD
applicants shall have experience in semiconductor processing, circuit
design and system integration. Additionally it is expected that the PhD
student contributes to teaching, administrative and operational tasks of
the Chair. Admission and acceptance of an applicant as a PhD student or
doctoral candidate at ETH Zurich depends on the fulfillment of all
pre-requisites and regulations of ETH Zurich https://www.ethz.ch/en/doctorate.html .
The candidate
holds a Diploma or Master of Science degree in electrical or mechanical
engineering, physics or material science. She or he has substantial
experience in micro or nanosystems, semiconductor process technology,
circuit design and electrical / thermal characterization, based a
student thesis in the field. The candidate’s scientific record
demonstrates already excellence by a minimum of one first author journal
publication or a conference contribution.
She or he
should have very good English knowledge, experience in presenting
scientific results and excellent communication skills. The candidate is a
perfect team player and acts on her or his own initiative.
Entrance and duration:
Entrance upon availability, limited contract ETH Zurich rules apply
