Scientists at IBM invent thermometer for nanoscale

newSource  :

The IBM lab responsible for inventing the scanning tunneling microscope and the atomic force microscope has invented another critical tool for helping us understand the nanoworld.


Accurately measuring the of objects at the nanoscale has been challenging scientists for decades. Current techniques are not accurate and they typically generate artifacts, limiting their reliability.

Motivated by this challenge and their need to precisely characterize the temperature of new transistor designs to meet the demand of future cognitive computers, scientists in Switzerland from IBM and ETH Zurich have invented a breakthrough technique to measure the temperature of nano- and macro-sized objects. The patent-pending invention is being disclosed for the first time today in the peer-review journal Nature Communications, “Temperature mapping of operating nanoscale devices by scanning probe thermometry.”

A History of Invention

In the 1980s, IBM scientists Gerd Binnig and the late Heinrich Rohrer wanted to directly explore a surface’s electronic structure and imperfections. The instrument they needed to take such measurements didn’t exist, yet. So they did what any good scientist would do: they invented one. It became known as the scanning tunneling microscope (STM), opening the door to nanotechnology. Just a few years later, the invention was recognized with the highest of honors, the Nobel Prize for Physics in 1986.

Temporary Scientist position in Lund University, Sweden – PhD must, Python knowledge must

Lund University, ,

Lund University was founded in 1666 and for a number of years has been ranked among the world’s top 100 universities. The University has 42 000 students and more than 7 500 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.

MAX IV Laboratory has operated successfully for almost 30 years and is currently completing the new MAX IV synchrotron facility in Lund.
More than 1000 scientists from Sweden and the rest of the world are coming to the MAX IV Laboratory every year to use the x-rays produced by our electron accelerators. They do research in areas such as materials science, structural biology, chemistry, and nanotechnology. 190 people are currently employed at the MAX IV Laboratory. MAX IV is the largest and most ambitious Swedish investment in national research infrastructure. It will be the brightest source of x-rays worldwide when inaugurated June 2016 and will replace the existing laboratory, which today consists of the storage ring MAX I, II and III. MAX IV Laboratory is hosted by Lund University.

NanoMAX – the hard x-ray nanoprobe beamline of MAX IV will fully exploit the exceptionally low emittance, high brilliance and coherence properties of the X-ray source to produce tightly focused and coherent beams. The beamline will feature two experimental stations, one providing beam down to 10 nm size in vacuum environment, the other providing high flux nanobeams in the 100-200 nm size range and compatible with flexible sample environment.

The beamline is currently under construction. The installation of the experimental stations and the commissioning of the beamline will take place during 2016. The beamline is expected to get first users in 2017. Once operational at its full capabilities, the beamline will enable nm- resolution imaging applications in diverse fields ranging from nano-science to environmental and life science, exploiting (coherent) scattering contrast, fluorescence and absorption.

The implementation and the development of analysis tools for coherent diffraction data is an essential part of the work needed to prepare the beamline towards this goal. Within this scope, we are now seeking to hire a Scientist with a background in (coherent) X-ray diffraction and/or imaging techniques and experience in programming. The successful candidate will join the NanoMAX team with the main task of implementing and developing imaging reconstruction software. She/he will test the developed routines on the first data acquired at NanoMAX and will support the beamline initial users. This work will be done in close interaction with the IT group of MAX IV and within international collaborations, including other synchrotron facilities.

• You will adapt and enable existing software for coherent x-rays diffraction data analysis for the use at NanoMAX, in close collaboration with MAX IV’s IT group.
• You will develop software for data analysis, following MAX IV’s programming standards, if suitable codes do not exist.
• You will perform coherent diffraction imaging experiments at NanoMAX and at other facilities.
• You will participate to the commissioning and operation of the beamline and provide support to external users during operation.

• You hold a PhD in natural sciences in subjects of relevance for NanoMAX.
• You have good knowledge in x-ray diffraction and/or imaging methods.
• You have experience in writing data analysis codes and/or programming in different computer languages.
• You have a demonstrated ability to work independently.
• You have good command of English, good communication and team working skills.

The following qualifications are considered an asset:
• Experience with coherent diffraction imaging methods.
• Experience in writing scientific software, particularly in Python.
• Experience with hardware programming and/or interfacing.
• Experience with the use of nanobeams and/or of other x-ray based techniques of relevance for NanoMAX.

The University has individual salary. Please state requested salary in your application.
