Spice Simulation of Substrate Minority Carriers Propagation with Equivalent Electrical Circuit

Maher Kayal, Jean-Michel Sallese, Camillo Stefanucci, Pietro Buccella

This paper presents an equivalent electrical circuit for one dimensional substrate minority carriers spice simulation. The electrical circuit parameters are extracted from substrate meshing applying the finite difference method. This model is derived from ...

Amorphous silicon enhanced metal-insulator-semiconductor contacts for silicon solar cells

Aïcha Hessler-Wyser, Stefaan De Wolf, Bénédicte Demaurex

Carrier recombination at the metal-semiconductor contacts has become a significant obstacle to the further advancement of high-efficiency diffused-junction silicon solar cells. This paper provides the proof-of-concept of a procedure to reduce contact recom ...

From All-Si Nanowire TFETs Towards III-V TFETs

Hesham Ghoneim

Performance improvement by device scaling has been the prevailing method in the semiconductor industry over the past four decades. However, current silicon transistor technology is approaching a fundamental limit where scaling does not improve device perfo ...

Beyond Scaling

Luca De Michielis

Over the recent decades, the balance between increasing the complexity of computer chips and simultaneously reducing cost per bit has been accommodated by down-scaling. While extremely successful in the past, this approach now faces grave limitations leadi ...

Multi-gate Si nanowire MOSFETs

Mohammad Najmzadeh

Multi-gate devices e.g. gate-all-around (GAA) Si nanowires and FinFETs are promising can- didates for aggressive CMOS downscaling. Optimum subthreshold slope, immunity against short channel effect and optimized power consumption are the major benefits of s ...

Optimization of electric shunt resonant circuits for electroacoustic absorbers

Hervé Lissek, Romain Boulandet, Etienne Thierry Jean-Luc Rivet

Sound absorption can be achieved in a relatively simple manner with passive or active electroacoustic absorbers. Electroacoustic absorbers are basically loudspeakers, the membrane of which is used as an absorber/reflector of sound, and the electric termina ...
