Two-dimensional (2D) materials are a new type of materials under intense study because of their interesting physical properties and wide range of potential applications from nanoelectronics to sensing and photonics. Monolayers of semiconducting transition ...
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 ...
This thesis explores the electronic properties of one layered transition-metal dichalcogenide – single-layer MoS2, and demonstrates the first transistors and integrated circuits with characteristics that outperform graphene electronics in many aspects and ...
We perform scanning photocurrent microscopy on WS2 ionic liquid-gated field effect transistors exhibiting high-quality ambipolar transport. By properly biasing the gate electrode, we can invert the sign of the photocurrent showing that the minority photoca ...
The increase of components density in advanced microelectronics is practically dictated by the device size and the achievable pitch between the devices. Scaling down dimensions of devices and progress in the circuit design allowed following Moore's law dur ...
As we advance into the era of nanotechnology, semiconductor devices are scaled down to their physical limits, thereby opening up venues for new transistor channel materials based on nanowires and nanotubes. Transistors based on nanowires and nanotubes inhe ...
Flexible transistors and circuits based on dinaphtho-[2,3-b:2',3'-f]thieno[3,2-b]thiophene (DNTT), a conjugated semiconductor with a large ionization potential (5.4 eV), are reported. The transistors have a mobility of 0.6 cm(2) V-1 s(-1) and the ring osci ...
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 ...
The analysis of transparent conducting oxide nanostructures suffers from a lack of high throughput yet quantitatively sensitive set of analytical techniques that can properly assess their electrical properties and serve both as characterization and diagnos ...
We present a new electronic device – the single-electron bipolar avalanche transistor (SEBAT) – which allows for the detection of single charges with a bandwidth typically above 1 GHz, exceeding by far the bandwidth of other room-temperature single-electro ...
