Phonon Driven Ferroelectricity and Raman Active Modes in Hybrid Organic‐Inorganic Perovskites

open access: yesAdvanced Materials, EarlyView.
Ferroelectric domains, a hallmark of ferroelectricity, are studied using temperature‐dependent Raman spectroscopy to uncover characteristic phonons associated with ferroelectric phase transitions in different n‐value HOIPs. Higher n‐value HOIP demonstrate a reduced ferroelectric switching energy barrier, providing valuable insights for optimizing ...

Charge Transport and Carrier Polarity Tuning by Electrolyte Gating in Nickel Benzenehexathiol Coordination Nanosheets

open access: yesAdvanced Materials, EarlyView.
This work reveals that charge transport in nickel benzenehexathiol coordination nanosheets is governed by variable‐range hopping reflecting structural disorder. Electrolyte gating induces a switch in dominant carrier polarity from p‐type to n‐type and leads to an improvement in thermoelectric performance.
