©2018 by Device Spectroscopy Laboratory

Welcome to the Device Spectroscopy Lab

The Device Spectroscopy Laboratory, DSL, here at Bar-Ilan University is focused on spectroscopy of nanoscale materials and devices composed of such materials.  Our efforts are concentrated on understanding and tailoring light-matter interactions at the most fundamental level, and then on parlaying these insights into useful devices.

 
 

Congratulations to Tal Ben Uliel for completing her masters and starting her PhD at Neuroengineering & Regeneration Lab. We wish her great success in her doctoral research.

Research Interests and Scientific Activities

Major research interest at Device Spectroscopy Laboratory is studying and tailoring light-matter interactions inside of nanoscale devices.  The devices are not restricted to lasers and LEDs, but can even be microcavities, semiconductor nanostructures or biological materials such as proteins and bacteria.

Coherent Light-Matter Interactions

At our group, we intensively study CLM Interactions. We are interested in using microcavity devices to enhance light-matter interactions, such as for strong light-matter coupling in the mid-infrared, and for monolayer lasers.

Near-Field Spectroscopy

In an effort to gain a better understanding of materials at nano-scale spatial resolution, we employ techniques such as NSOM, dual SPM probe AFM:NSOM, and TERS (Tip-Enhanced Raman Scattering).

Applied Spectroscopy

We develop the methodologies of Low-Frequency Raman  Spectroscopy for characterizing nanostructured materials, such as organic, semiconducting, perovskite, biological and organic/inorganic hybrids. We also investigate methods of enhancing Raman scattering.

 

Ongoing Research Projects

 

Coherent Infrared Emission from Organic Materials

Team

We are a team of researchers, including students, post-docs, and staff scientists, that are passionate about multiple domains of science, ranging from chemistry and materials to physics and optics.  Most of all, we enjoy working together and striving to have a positive and meaningful impact on society.

The magic of DSL is the students and staff.  Thankfully, I have students and staff who come with a high aptitude for scientific work and who possess tremendous desire to succeed.  I have also learned not only to manage students, but to nurture them, motivate them, and lead them, and ultimately empower them to be independent scientific thinkers, doers, and leaders.  I have found that success is a natural by-produce of character, and so I promote building the character of the people in my lab, to help them expand their comfort zones, to work together as a team, and to develop the desire to attain personal and collective goals.  In my opinion, the lab is a powerhouse in the subject areas of device spectroscopy. To the greatest extent possible, we also share our expertise in spectroscopy, joining forces with other labs in collaborations and in providing assistance to meet their characterization needs.
