About
The program of the National Institute of Science and Technology in Semiconductor Nanodevices – DISSE encompasses the study and development of nanostructures for the manufacture of optoelectronic devices with an emphasis on infrared photodetectors and novel devices based on purely quantum effects that have not yet been explored. The group has consolidated itself as a center for III-V semiconductor epitaxy, by producing a wide variety of infrared photodetectors operating in different ranges and
optimizing different figures of merit, and advanced the understanding of quantum effects that can be used in devices of tomorrow.
DISSE successfully fulfilled its missions in research, training of human resources, transfer of acquired knowledge to companies and/or government agencies and scientific dissemination.
PUC-Rio (CETUC)
LabSem (Semiconductor Laboratory), in addition to being the INCT headquarters, concentrates all MOVPE growth activities, processing and characterization of samples and devices produced in the laboratory and which supplies several DISSE groups.
USP (Physics)
The LNMS (Laboratory of New Semiconductor Materials) is the other DISSE laboratory responsible for sample growth activities using MBE, as well as their processing and characterization before being sent to other DISSE groups.
UFRJ (Physics)
The UFRJ group is responsible for photoluminescence and AFM measurements, for studying the influence of ionizing radiation on the final performance of the devices, and for the use of computational intelligence to optimize growth conditions.
UFRJ (Chemistry)
Responsible for developing computational tools for optimizing the growth and properties of optoelectronic devices. This is an emerging group nucleating.
CTA (IEAv)
The Radiometry and Sensor Characterization Laboratory carries out more rigorous and systematic characterization of some of the best sensors developed by DISSE, while the Semiconductor Device Characterization Laboratory, which works in line with the first, aims to supplement the manufacturing and characterization of infrared sensor arrays. The Virtual Engineering Laboratory develops end-user friendly computational codes that can be accessed from an online platform to evaluate the properties of complete devices such as infrared sensors or solar cells.
UFMG (Physics + Electrical Engineering + Computer Science)
The institution houses several groups and laboratories associated with DISSE: the Photonics, Physics of Low-Dimensional Semiconductor Systems and Processing Laboratories are responsible for lines of basic research related to photonic crystals, optical microcavities and polaritons. The Laboratory for Optronics and Applied Microtechnologies (OptMAlab) is responsible for developing the reading integrated circuit (ROIC) to control the input and output signals of the sensor arrays manufactured by DISSE. The group from the Department of Computer Science is tasked with developing computational tools to optimize growth conditions, manipulate experimental data related to each sample grown, and optimize the performance of some devices.
UFRJ: Xerém Campus (Physics)
The recent UFRJ campus is responsible for the characterization of mid-band solar cells and the manufacture of hybrid cells.
CTEx (LOS)
The Technology Center’s Optronics and Sensors Laboratory is responsible for device encapsulation activities.
