Two-dimensional ferroelectric materials have emerged as a promising candidate for the
development of next-generation photodetectors owing to their inherent photogalvanic effect …

The bulk photovoltaic effect, with ultra‐sensitive control under ambient piezo response,
plays a significant role in many modern optoelectronic applications. However, functional …

Motivated by the recent synthesis of a new polymorph of germanium selenide (γ-GeSe) with
a honeycomb lattice and an astonishingly high conductivity (even higher than graphite) …

Noncentrosymmetric crystals are generally endowed with the potential to spontaneously
generate photocurrent responses through the intrinsic bulk photovoltaic effect, thereby …

The bulk photovoltaic effect (BPVE) in layered materials has garnered widespread attention
due to its large shift current responses and promising potential for efficient photoelectric …

We investigate the stable structure and optoelectronic properties of thin γ-GeSe layers
through first-principles calculations. We examine three stacking configurations (AA, AB, and …
