In this talk, I will cover our investigations on halide perovskite memristors for computing and hardware security. The first part of the talk will focus on designing diffusive and drift halide perovskite memristive barristors as nociceptive and synaptic emulators for neuromorphic computing [1]. Here, we will discuss the role of interfaces that play pivotal roles in determining the switching characteristics of perovskite memristors, demonstrations of nociceptors and synapses using halide perovskite memristors and their integration with robotics for in-sensory computing. In the second part of the talk, we will discuss the use case of perovskite memristors for Physical Unclonable Functions (PUFs)- a security primitive exploiting the switching physics of one-dimensional halide perovskites as excellent sources of entropy for secure key generation and device authentication [2].

MATSUS

Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.

International Conference on Hybrid and Organic Photovoltaics

International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.

Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics

The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
