Reducing the interface barrier between metals and semiconductors is crucial for designing high-performance optoelectronic devices based on van der Waals heterojunctions (HJs). This study proposes four models of HJs composed graphene (GR) Ga2X3 (X = S, Se) systematically investigates their electronic properties, along with strain engineering electric field effects. The results indicated that exploiting dipole-induced potential step allows modulation Schottky height (SBH) contact type by...
Heterojunctions (HJs) based on two-dimensional (2D) transition metal dichalcogenides are considered promising candidates for next-generation electronic and optoelectronic devices. Here, vertical (V-type) lateral (L-type) HJ diodes metallic 1T-VSe2 semiconducting 2H-WSe2 with out-of-plane in-plane contacts designed. First-principles quantum transport simulations reveal that both V- L-type VSe2/WSe2 form p-type Schottky contacts. Under zero gate voltage, V-type exhibit superior spin...
Multi-step creep tests and multi-step stress relaxation were performed on polyvinylchloride samples. Acoustic emission signals monitored to assess the damage evolution in tested samples, an interesting phenomenon, named here as ‘acoustic hysteresis effect’, was found both tests. The observed acoustic behaviour indicates that polymers is time dependent, effect attributed viscoelasticity time-dependent material. more marked of material, greater effect.
