Carrier Mapping in Sub-2nm Node Nanosheet Transistors with Scanning Spreading Resistance Microscopy. [PDF]
Small MethodsWithin this work, advancements in scanning spreading resistance microscopy (SSRM) allow charge carrier mapping within 5.5 nm‐thick nanosheet channels. Devices subjected to rapid thermal annealing at 950°C show ∼ 5 nm enhanced phosphorus diffusion, with profiles in close agreement with semi‐atomistic process simulations.

Transimpedance Amplifier [Circuit Intuitions] [PDF]
IEEE Solid-State Circuits Magazine, 2020 Discusses the technology of a transimpedance amplifier (TIA). A TIA is a two-port device that converts an input current in one port to an output voltage in another port. A TIA is expected to have a low input impedance, so as to absorb all the current produced by the PD, and a high output impedance, so as to have a high gain. We reviewed two TIA designs
