Study of extrinsic doping in high operating temperature (HOT) HgCdTe photodetectors

Offer N°: SL-DRT-14-0752

Start date: 1 Oct 2014

CEA/Leti is, in collaboration with the Grenoble based company Sofradir, one of the world leaders in the research and development of Infrared photodetectors made in the II-VI semi-conductor HgCdTe. One of the main challenges in this field is the increase in operating temperature of the detectors. Theoretically, the highest operating temperature in HgCdTe photodiodes should be achieved in extrinsically doped material.


Hardware virtualization of Input-Output Peripherals in micro-servers for Big-Data applications.

Offer N°: SL-DRT-14-0498

Start date: 1 Sep 2014

Massively parallel computer servers have experienced strong growth since the 70s. Initially dedicated to high performance computing (Cray and CDC Super Computers) and telecommunications (first e-mail computer servers in 1975), many servers are nowadays used for the storage and processing of information (eg. Google, Facebook ...). With the increase in size of these servers, power consumption has become a major concern.


Sub 100 nm resolution 3D Imprinting/patterning process development for microelectronics, MEMS and optoelectronics applications

Offer N°: SL-DRT-14-0607

Start date: 1 Sep 2014

NanoImprint Lithography, based on the use of a nanopatterned stamp, has been developed to 2D or advantageously 3D (discrete or analog) patterns within polymer layer. Transferring these patterns within the underlying active layer or substrate without affecting the exact shapes and dimensions remains still challenging. During this thesis, a disruptive approach, based on localized plasma treatment, will be investigated to perform such transfer.


Acoustic trap micro fluidic realization for biological applications using thin film membranes

Offer N°: SL-DRT-14-0571

Start date: 1 Aug 2014

In biology, it is a real challenge to be able to manipulate easily and without damage objects such as cells, bacteria and so forth. Indeed, most biological tasks (centrifugation, concentration, sorting...) rely on this capability. Acoustic waves are a very good candidate since ultrasound is a non-invasive technique, compatible and insensitive to electrical charges present in biological Medias.
