Bandgap‐Dependent Band‐to‐Band Tunneling in Carbon Nanotube Transistors

Advanced Materials Interfaces, EarlyView.
We systematically investigate bandgap‐dependent BTBT in SWCNT transistors by comparing wide‐bandgap (6,5) (Eg≈1.13 eV), medium‐bandgap HiPco, and narrow‐bandgap Arc‐discharge (Eg≈0.59 eV) SWCNT networks. The narrow‐bandgap networks show stronger BTBT, higher off‐state leakage, and lower on/off ratio, while wide‐bandgap (6,5) devices suppress BTBT and ...

Cation‐π Interaction‐Based Biointerface for Low‐Cost PD‐1 Detection Toward NSCLC Immunotherapy Monitoring

Advanced Materials Interfaces, EarlyView.
A cation‐π interaction‐based biointerface is engineered on a CNT‐FET for label‐free detection of PD‐1. PD‐1 monoclonal antibodies are orientedly immobilized via cation‐π interactions between PCz‐wrapped semiconducting single‐walled carbon nanotubes and the Fc region of the monoclonal antibody.

The Role of Charge Transfer and Linker States in the Magnetoluminescence of a Diradical With Two Spatially Proximate Triarylmethyl Units

Advanced Optical Materials, EarlyView.
Magnetoluminescent (ML) diradicals exhibit field‐dependent emission due to magnetic field‐dependent spin state populations and spin‐dependent emission properties. In this work, quantum chemical calculations applied to the first reported ML diradical provide evidence of the different deactivation pathways of the excited singlet and triplet states and ...
