Main research topics
1) Development of infrared photodetectors operating in the 2 to 20 μm
range for different applications.
2) Investigation of fundamental properties of quantum dot structures for
infrared photodetectors.
3) Control of the growth of self-assembled quantum dots.
4) New physical phenomena in semiconductor quantum dots for novel
devices.
Summary of achievements and perspectives
1) Theoretical modeling and computational tools were developed.
2) Photodetectors for different operation wavelengths using a great
variety of quantum dot structures were fabricated.
3) Photodetector for CO2 gas detection was developed.
4) Circuits for assembling and integrating photodetectors were tested and
should be improved.
5) Trustful methods for responsivity measurements were established.
6) Different carrier extraction mechanisms from quantum dot structures
were investigated.
7) A photocurrent measurement set-up using monochromatic light source
was implemented.
8) The new epitaxial growth equipment was specified and acquired to
be delivered by the end of 2010 and construction for its installation is
underway.
9) Anodic oxidation and atomic force microscopy were successfully used
to spatially control the nucleation of quantum dots.
10) Computational intelligence techniques were applied to the epitaxial
growth of quantum dots and a methodology for its application was
established.
11) Fano interference in the reflectivity of L3 type photonic crystals was
observed and controlled by the polarization of the incident light.
12) Improvement in the quality factor of microcavities increasing the
polariton lifetime and, consequently, reducing the operation threshold of
devices was achieved.
13) Coupling of neighboring quantum dots in microcavities via the cavity
modes was observed.

Summary of achievements and perspectives
The INCT of Nanotechnology for Integrated Markers (INAMI) has been
operating since January 2009, complying with the edictal of the National
Institutes of Science and Technology program launched by the Ministry of
Science and Technology (MCT) through CNPq, altogether with CAPES and Fluorometer dedicated to the detection of luminescent markers based
state FAPs. The INAMI had a very positive balance regarding investments
and results achieved by the institute in the strengthening of cooperation
among researchers, human resources training, scientific production
and, above all, in the changing of knowledge into innovative processes
and devices that, in a near future, may provide social benefits of great
relevance. Moreover, INAMI was successful in the elaboration and
planning of scientific and technological actions. INAMI, with well-focused
acting themes, began, in an intense way, actions of rapprochement with
on rare earths ions.

the entrepreneurs sector, through the offer of results with great potential
for technological applications. It is worth enhancing the importance of DTI
and ITI scholarships in this process.
