Prof. Dr. Walter M. Weber is going to give a talk on "Nanoelectronic computing opportunities beyond CMOS era".

Silicon and germanium nanowires with diameters down to 3 nm exceptionally combine unique one-dimensional electronic transport properties with the mature material know-how of highly integrated semiconductor processing technology. In addition of providing conduction channels that can bring conventional field effect transistors to the ultimate scaling limits, the physics of group IV nanowires endow the realization of novel electronic device and sensor principles. To truly exploit the exceptional properties for sensing and logic computation, such innovations need to be driven across the research value chain of electronics by engineering their integrability in modern semiconductor manufacturing flows, by building and testing reliable circuits and by verifying system compatibility under realistic conditions. Throughout this presentation, I will show concepts developed in my research group based on atomically abrupt nano-junctions and strain induced phenomena in semiconductor nanowires enabling reconfigurable electronics for beyond CMOS computing as well as hardware security applications.

In his Science Talk, Venkata Pathuri Bhuvan is going to talk about "Joint Calibration and Tomography based on Separable Least Square Approach".

Most of the existing tomography/reconstruction techniques rely on accurate calibration to reconstruct the features of interest. In several industrial applications, the calibration is typically performed off-line and has to be repeated frequently to counter time varying perturbation caused by aging, varying operating conditions, and so on. In this talk, a novel online joint calibration and tomography based on variable projection (VP) based separable least squares (LS) approach with constraints on linear and non-linear parameters is proposed. The imposition of constraints on the linear parameters improves the estimation accuracy of the ill-posed and under determined tomography problem. The constraints on the non-linear parameters restricts the proposed method from departing far away from the initial guess especially, when a good initial guess is available. Further, few selected results on time of flight acoustic tomography and simultaneous calibration of the acoustic transducer positions using the proposed methodology are presented.
