Interfacial energy band bending and carrier trapping at the vacuum-deposited MAPbI3 perovskite/gate dielectric interface

open access: yesResults in Physics, 2018
We report energy band bending of methylammonium lead halide (MAPbI3) perovskite film in contact with indium-tin-oxide (ITO) surface using photoelectron spectroscopy in air (PESA) and ultraviolet photoelectron spectroscopy (UPS) measurements.

Silver Ions as Ambipolar Dopants in InAs Nanocrystal Solids. [PDF]

open access: yesAdv Mater
Ag⁺ ions post‐introduced into InAs nanocrystal films act as ambipolar dopants whose effect depends on host polarity and dopant concentration. In n‐type InAs nanocrystal films, Ag⁺ occupies interstitial sites to yield n‐type doping effect, whereas in Zn‐doped p‐type InAs nanocrystal films, it first forms p‐type surface doping effect and later induces n ...

Trapped Particle Stability for the Kinetic Stabilizer

open access: yes, 2011
A kinetically stabilized axially symmetric tandem mirror (KSTM) uses the momentum flux of low-energy, unconfined particles that sample only the outer end-regions of the mirror plugs, where large favorable field-line curvature exists.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Dual‐Gate Anti‐Ambipolar Transistor with Van der Waals ReS2/WSe2 Heterojunction for Reconfigurable Logic Operations

open access: yesAdvanced Electronic Materials, 2023
A dual‐gate anti‐ambipolar transistor (AAT) with a two‐dimensional ReS2 and WSe2 heterojunction is developed. The characteristic Λ‐shaped transfer curves yielded by the bottom‐gate voltage are effectively controlled by the top‐gate voltage.

A Numerical Study of Scaling Issues for Schottky Barrier Carbon Nanotube Transistors

open access: yes, 2003
We performed a comprehensive scaling study of Schottky barrier carbon nanotube transistors using self-consistent, atomistic scale simulations. We restrict our attention to Schottky barrier carbon nanotube FETs whose metal source/drain is attached to an ...

Selective Charge Injection via Topological van der Waals Contacts for Barrier‐Free p‐Type TMD Transistors

open access: yesAdvanced Functional Materials, EarlyView.
 Topological van der Waals contacts represent a new class of electrodes for 2D semiconductors, enabling precise control of the Schottky barrier height (SBH) and contact resistance (RC) through interlayer distance and orbital hybridization engineering. In Se‐based transition metal dichalcogenides, these contacts achieve an ultralow SBH of 7 meV, RC of 0.

Lateral energy band profile modulation in tunnel field effect transistors based on gate structure engineering

open access: yesAIP Advances, 2012
Choosing novel materials and structures is important for enhancing the on-state current in tunnel field-effect transistors (TFETs). In this paper, we reveal that the on-state performance of TFETs is mainly determined by the energy band profile of the ...
