Dielectric/Semiconductor Interfacial p-Doping: A New Technique to Fabricate Solution-Processed High-Performance 1 V Ambipolar Oxide Transistors

Chourasia, N.K.; Sharma, A.; Pal, N.; Biring, S.; Pal, B.N. (Wiley-VCH Verlag, 2020-10-01)

Herein, dielectric/semiconductor interfacial p-doping is used to develop a high-carrier-mobility and balanced ambipolar tin oxide (SnO2) thin-film transistor (TFT). To introduce this interfacial doping, TFTs are fabricated ...
A Lithography-Free Fabrication of Low-Operating Voltage-Driven, Very Large Channel Length Graphene Field-Effect Transistor with NH3Sensing Application

Chourasia, N.K.; Singh, A.K.; Rai, S.; Sharma, A.; Chakrabarti, P.; Srivastava, A.; Pal, B.N. (Institute of Electrical and Electronics Engineers Inc., 2020-10)

Large-area-based field-effect transistor (FET) gas sensor has the potential to provide a larger sensing area for a chemical analyte. So far, graphene FETs (GFETs) are mostly fabricated by expensive lithographic techniques ...
Role of electronically coupled in situ grown silver sulfides (Ag2S) nanoparticles with TiO2 for the efficient photoelectrochemical H2 evolution

Singh, S.V.; Gupta, U.; Mukherjee, B.; Pal, B.N. (Elsevier Ltd, 2020-11-06)

A solution-processed in situ grown synthesis method has been developed to grow electronically coupled silver sulfide (Ag2S) nanoparticles (NPs) inside a titanium oxide (TiO2) thin film. Taking the advantage of better charge ...
Scalable Synthesis of a Sub-10 nm Chalcopyrite (CuFeS2) Nanocrystal by the Microwave-Assisted Synthesis Technique and Its Application in a Heavy-Metal-Free Broad-Band Photodetector

Kumar, B.; Singh, S.V.; Chattopadhyay, A.; Biring, S.; Pal, B.N. (American Chemical Society, 2020-10-13)

A heavy-metal-free chalcopyrite (CuFeS2) nanocrystal has been synthesized via microwave-assisted growth. Large-scale nanocrystals with an average particle size of 5 nm are fabricated by this technique within a very short ...

Kumar, B.; Singh, S.V.; Chattopadhyay, A.; Biring, S.; Pal, B.N. (American Chemical Society, 2020-10-13)

A heavy-metal-free chalcopyrite (CuFeS2) nanocrystal has been synthesized via microwave-assisted growth. Large-scale nanocrystals with an average particle size of 5 nm are fabricated by this technique within a very short ...
Solution processed Cu2S/TiO2 heterojunction for visible-near infrared photodetector

Singh, S.V.; Sharma, A.; Biring, S.; Pal, B.N. (Elsevier B.V., 2020-09-30)

A new method has been developed to grow copper (I) sulfide (Cu2S) nanoparticle (NP) inside a titanium dioxide (TiO2) thin film. This Cu2S NP growth process consists of two successive steps: ion-exchange and sulfurization ...
Volume 10, Issue 8, 1 August 2020, Article number 085313 Lithography-free fabrication of low operating voltage and large channel length graphene transistor with current saturation by utilizing Li+of ion-conducting-oxide gate dielectric

Chourasia, N.K.; Singh, V.K.; Sharma, A.; Srivastava, A.; Pal, B.N. (American Institute of Physics Inc., 2020-08-01)

The large channel length graphene field-effect transistor (GFET) can outperform its competitors due to its larger active area and lower noise. Such long channel length devices have numerous applications, e.g., in photodetectors, ...
